CHAPTER 9
During the administration of President James Buchanan, 1857-61, tensions over the issue of extending slavery into the western territories mounted alarmingly and the nation ran its inexorable course toward disunion. Along with slavery, the shifting social, economic, political, and constitutional problems of the fast-growing country fragmented its citizenry. After open warfare broke out in Kansas Territory among slaveholders, abolitionists, and opportunists, the battle lines of opinion hardened rapidly. President Buchanan quieted Kansas by using the Regular Army, but it was too small and too scattered to suppress the struggles that were almost certain to break out in the border states.
In 1859 John Brown, who had won notoriety in "Bleeding Kansas," seized the federal arsenal at Harpers Ferry a mad attempt to foment a slave uprising within a slaveholding state. Again federal troops were called on to suppress the new outbreak, and pressures and emotions rose on the eve of the 1860 elections. Republican Abraham Lincoln was elected to succeed Buchanan; although he failed to win a majority of the popular vote, he received 180 of the 303 electoral votes. The inauguration that was to vest in him the powers of the Presidency would take place March 4, 1861. During this lame-duck period, Mr. Buchanan was unable to control events and the country continued to lose its cohesion.
Abraham Lincoln's election to the Presidency on November 6, 1860, triggered South Carolina on December 20 to enact an ordinance declaring "the union now subsisting between South Carolina and other States, under the name of the 'United States of America,' is hereby dissolved." Within six weeks, six other deep-South states seceded from the Union and seized federal property inside their borders, including military installations, save Fort Pickens outside Pensacola and Fort Sumter in Charleston Harbor. To the seven states that formed the Confederate States of America on February 18, 1861, at Montgomery, Alabama, retention of the forts by the U.S. Government was equivalent to a warlike act. To provide his fledgling government with a military force, on on March 6 the new Confederate Executive, Jefferson Davis, called for a 100,000-man volunteer force to serve for twelve months.
The creation of a rival War Department south of the 35th parallel on February 21 shattered the composition of the Regular Army and disrupted its activities, particularly in Texas, where Maj. Gen. David E. Twiggs surrendered his entire command. With an actual strength of 1,080 officers and 14,926 enlisted men on June 30, 1860, the Regular Army was based on 5-year enlistments. Recruited heavily from men of foreign birth, the United States Army consisted of 10 regiments of infantry, 4 of artillery, 2 of cavalry, 2 of dragoons, and 1 of mounted riflemen. It was not a unified striking force. The Regular Army was deployed within seven departments, six of them west of the Mississippi. Of 198 line companies, 183 were scattered in 79 isolated posts in the territories. The remaining 15 were in garrisons along the Canadian border and on the Atlantic coast. . . .
The roster of the Regular Army was altered considerably by Davis' action in creating a Confederate Army. Of the active officer corps numbering 1,080, 286 resigned or were dismissed and entered the Confederate service. (At least 26 enlisted men are known to have violated their oaths.) West Point graduates on the active list numbered 824; of these, 184 were among the officers who offered their swords to the Confederacy. Of the approximately 900 graduates then in civil life, 114 returned to the Union Army and 99 others sought southern commissions. General in Chief Scott and Col. George H. Thomas of Virginia were Southerners who fought for the Union. More serious than their numbers, however, was the high caliber of the officers who joined the Confederacy; many were regimental commanders and three had commanded at departmental level.
With military preparations under way, Davis dispatched commissioners to Washington a few days after Lincoln's inauguration on March 4, 1861, to treat for the speedy takeover of Forts Sumter and Pickens. Informally reassured that the forts would not be provisioned without proper notice, the envoys returned to Montgomery expecting an uneventful evacuation of Sumter. President Lincoln had to move cautiously, for he knew Sumter's supplies were giving out. As each March day passed, Sumter aggravated the harshness of Lincoln's dilemma. In case of war, the fort had no strategic value. If Lincoln reinforced it, Davis would have his act of provocation and Lincoln might drive eight more slaveholding states out of the Union. If Sumter was not succored, the North might cool its enthusiasm for the Union concept and become accustomed to having a confederation south of the Mason-Dixon line.
President Lincoln spent a fortnight listening to the conflicting counsel of his constitutional advisers, and made up his own mind on March 29 to resupply Fort Sumter with provisions only. No effort would be made to increase its military power. By sea he soon dispatched a token expedition and on April 8 notified South Carolina's governor of his decision. The next move was up to the local Confederate commander, Brig. Gen. Pierre G. T. Beauregard. On the 11th, Maj. Robert Anderson, Sumter's commander, politely but firmly rejected a formal surrender demand. At 4:30 the next morning Confederate batteries began a 34-hour bombardment. Anderson's 90-man garrison returned it in earnest, but Sumter's guns were no match for the concentric fire from Confederate artillery. Offered honorable terms on April 14, Anderson surrendered the federal fort, saluted his U.S. flag with fifty guns, and, with his command, was conveyed to the fleet outside the harbor to be taken to New York City.
Unquestionably, the Confederates fired the first shot of the war, and with that rash act removed many difficulties from Lincoln's path to preserve the Union. On the 15th Lincoln personally penned a proclamation declaring the seven southern states in insurrection against the laws of the United States. To strangle the Confederacy, on the 19th Lincoln declared the entire coast from South Carolina to Texas under naval blockade. To augment the reduced Regular Army, Lincoln asked the governors of the loyal states for 75,000 militiamen to serve for three months, the maximum time permissible under existing laws. With a unanimity which astonished most people, the northern states responded with 100,000 men. Within the eight slave states still in the Union, the militia call to suppress the rebellion was angrily and promptly rejected, and the President's decision to coerce the Confederacy moved Virginia, North Carolina, Tennessee, and Arkansas to join it.
As spring changed into summer the magnitude of the job that the Union had proclaimed for itself--the conquest of an area the size of western Europe, save Scandinavia and Italy, defended by a plucky and proud people and favored by military geography--was imperfectly understood. Although Lincoln later emerged as a diligent student of warfare, he was as yet unversed in the art. His rival, Davis, from the outset knew his military men quite well and thoroughly understood the mechanics of building a fighting force. Yet, as time passed, Davis was to mismanage his government and its military affairs more and more.
Virginia's secession caused Col. Robert E. Lee, Scott's choice to be the Union's field leader, to resign his commission and offer his services to his state. The Confederates moved their capital to Richmond, Virginia, site of the largest iron works in the south and one hundred miles south of the Union capital, Washington. On May 23, Union forces crossed into northern Virginia, occupying Arlington Heights and Alexandria. With Virginia and North Carolina in rebellion, Lincoln extended the naval blockade and called for a large volunteer army backed by an increased Regular force.
Correctly anticipating that Congress in its session to open July 4 would approve his actions, Lincoln, on his own authority, established 40 regiments of U.S. Volunteers (42,034 men) to serve three years or for the duration of the war. He ordered the Regular Army increased by 1 regiment of artillery, 1 of cavalry, and 8 of infantry (actually, 9 regiments were added), or 22,714 men, and the Navy by 18,000 sailors. The new Regular infantry regiments were each to have 3 battalions of about 800 men, in contrast to the 1-battalion structure in the existing Regular and volunteer regiments. Because the recruits preferred the larger bonuses, laxer discipline, and easy-going atmosphere of the volunteers, most of the newly constituted regiments were never able to fill their additional battalions to authorized strength.
The enthusiastic response to Lincoln's various calls had forced him to ask the governors to scale down the induction of men. The overtaxed camps could not handle the increased manpower. In raising the Army Lincoln used methods that dated back to Washington's day. The combat efficiency and state of training, of the new units varied from good to very poor. Some militia regiments were well trained and equipped, others were regiments in name only. The soldiers often elected their own company officers, and the governors commissioned majors and colonels. The President appointed generals. Although many of the newly commissioned officers proved to be enthusiastic, devoted to duty, and eager to learn, incompetents were also appointed. Before the end of 1861, however, officers were being required to prove their qualifications before examining boards; those found unfit were allowed to resign.
Frequently advised by governors and congressmen, Mr. Lincoln selected generals from among leading politicians in order to give himself a broader base of political support. Some political generals, such as John A. Logan and Francis P. Blair, Jr., distinguished themselves, whereas others proved military hindrances. Lincoln gave a majority of the commissions in the first forty volunteer units to Regulars on active duty, to former West Pointers like George B. McClellan who had resigned to pursue a business career, or to those who bad held volunteer commissions during the Mexican War. On the other hand, Davis never gave higher than a brigade command to a Confederate volunteer officer until he had proved himself in battle.
Both North and South failed to develop a good system of replacement of individuals in volunteer units. The Confederacy, though hamstrung by its insistence that Texans be commanded by Texans and Georgians by Georgians and by governors' demands for retaining home guards, did devise a regimental system that stood up well until the closing days of the war. Except for Wisconsin, Illinois, and Vermont, the Union armies never had an efficient volunteer replacement system. As battle losses mounted and the ranks of veteran regiments thinned, commanders were forced to send men back to their home states on recruiting duty or face the disbandment of their regiments. Northern governors with patronage in mind preferred to raise new regiments, allowing battle-tested ones to decline to company proportions.
The enlisted Regular Army was kept intact for the duration of the war. Many critics believed that the Regulars should have been used to cadre the volunteer units. But this practice was initially impossible during the summer of 1861 for at least two reasons. Lincoln did not foresee a long war, and the majority of Regulars were needed on the frontier until trained men could replace them. In addition, Lincoln's critics overlooked the breakdown in morale that would have accompanied the breakup of old line regiments, many of which had histories and honors dating back to the War of 1812. An officer holding a Regular commission in 1861 had to resign to accept a commission in the volunteers unless the War Department specifically released him. Most Regulars were loath to resign, uncertain that they would be recalled to active duty after the war. Thus, during 1861 and part of 1862, promotion in the Regular Army was slow. All Regulars could accept commissions in the volunteers by 1862, and in many cases the year that they, had spent in small unit command seasoning had its rewards in advancing them to higher commands. Ulysses S. Grant and William T. Sherman, both U.S. Militarv Academy graduates returning from civilian life, asked specifically for volunteer regimental commands at first and soon advanced rapidly to general officer posts.
As North and South lined up for battle, clearly the preponderance of productive capacity, manpower, and agricultural potential lay on the side of the North. Its crops were worth more annually than those of the South, which had concentrated on growing cotton, tobacco, and rice. Between February and May 1861 the Confederate authorities missed the opportunity of shipping baled cotton to England and drawing bills against it for the purchase of arms. In seapower, railroads, material wealth, and industrial capacity to produce iron and munitions the North was vastly superior to the South. This disparity became even more pronounced as the ever-tightening blockade gradually cut off the Confederacy from foreign imports. The North had more mules and horses, a logistical advantage of great importance since supplies had to be carried to the troops from rail and river heads.
According to the census of 1860 the population of the United States numbered 31,443,321 persons. Approximately 23,000,000 of them were in the twenty-two northern states and 9,000,000 in the eleven states that later seceded. Of the latter total, 3,500,000 were slaves. The size of the opposing armies would reflect this disparity. At one time or another about 2,100,000 men would serve in the northern armies, while some 800,000 to 900,000 men would serve the South. Peak strength of the two forces would be about 1,000,000 and 600,000, respectively.
Yet not all the advantages lay with the North. The South possessed good interior lines of communications, and its 3,550-mile coast line, embracing 189 harbors and navigable river mouths, was most difficult to blockade effectively. Possessors of a rich military record in wars against the British, Spinish, Mexicans, and Indians, the Southerners initially managed to form redoubtable cavalry units more easily than the North and used them with considerable skill against the invading infantry. As the war moved along, the armies on both sides demonstrated high degrees of military skill and bravery. Man for man they became almost evenly matched, and their battles were among the bloodiest in modern history.
Jefferson Davis hoped that the sympathy or even intervention of European powers might more than compensate for the Confederacy's lack of material resources. This hope, largely illusory from the start, became less and less likely of realization with the emancipation of the slaves, with every Union victory, and with the increasing effectiveness of the blockade.
Militarily, the South's greatest advantage over the North was simply the fact that if not attacked it could win by doing nothing. To restore the Union the Federal forces would have to conquer the Confederacy. Thus the arena of action lay below the strategic line of the Potomac and Ohio Rivers. Here geography divided the theater of war into three interrelated theaters of operations. The eastern theater lay between the Atlantic Ocean and the Appalachian Mountains; the western theater embraced the area from the Appalachians to the Mississippi; and the trans-Mississippi theater ran westward to the Pacific Ocean.
In the east, the strategic triangle of northern Virginia shielded invasion routes. Its apex aimed arrowlike at the Federal capital; the Potomac River and the lower Chesapeake Bay formed its right leg; its left bounded on the Blue Ridge and the adjacent Shenandoah Valley; and the base of the triangle followed the basin of the James and Appomattox Rivers, whereon stood Richmond, halfway between the bay and the valley. For three and a half years Federal commanders would be defeated on the legs and in the center of this triangle as they tried to take Richmond and defeat the Army of Northern Virginia under Lee. In three neighboring counties within this triangle more than half a million men would clash in mortal combat; more would die in these counties than in the Revolutionary War, the War of 1812, the War with Mexico, and all the Indian wars combined. To bring the Confederates out of this triangle the North would have to execute an operation aimed at breaking through the base line along the James and Appomattox Rivers.
The hammer for swinging against the anvil of Virginia came from the line of the Ohio River as Union forces moved along the invasion routes of the Green, Cumberland, Tennessee, and Mississippi Rivers. To breach the lower reaches of the Appalachians, the Federals needed the railroad centers at Nashville, Chattanooga, and Atlanta; with them they could strike northward through the Carolinas toward the line of the James. But in the spring of 1861, the anvil and hammer concept had not yet occurred to the military leaders in Washington. Only the General in Chief, Winfield Scott, had a concrete strategic proposal for waging total war. He recommended to Lincoln that time be taken to train an army of 85,000 men and that the naval blockade of the Confederacy be enforced. Then the Army was to advance down the Mississippi to divide and conquer the South. The press ridiculed the strategy, calling it the Anaconda Plan. But few leaders examined the South in terms of its military geography or concentrated on a strategy to prevail over it. Instead, most thought in terms of political boundaries and a short war that would end with the capture of Richmond.
In the early summer of 1861 the partly trained 90-day militia, the almost untrained volunteers, and one newly organized battalion of Regulars--a total force Of 50,000 Federals commanded by Brig. Gen. Irvin McDowell--defended the nation's capital. Thirty miles to the southwest, covering the rail and road hub at Manassas, Virginia, General Beauregard posted some 20,000 Confederates, to be joined by 2,000 more within a few days. To the left, on their defensive line along the Potomac, the Confederates stationed another 11,000 men under Brig. Gen. Joseph E. Johnston in the Shenandoah Valley town of Winchester. Opposing Johnston around Martinsburg, with the mission of keeping the Confederates in place, was Maj. Gen. Robert Patterson with 18,000 Federals. On the extreme right of the Confederate northern Virginia defense line was Col. Joseph B. Magruder's force, which had recently repulsed Maj. Gen. Benjamin F. Butler's Union troops at Big Bethel, Virginia, on 10 June, and forced them back into their sanctuary at Fort Monroe.
Big Bethel, the first large-scale meeting engagement of the Civil War, demonstrated that neither opponent was as yet well trained. The Confederates had started preparations earlier to protect northern Virginia and therefore might have had a slight edge on their opponents. General McDowell, only recently a major of Regulars, had less than three months to weld his three types of units--militia, volunteer, and Regular--into a single fighting force. He attempted to do too much himself, and there were few competent staff officers in the vicinity to help him. McDowell's largest tactical unit was a regiment until just before he marched out of Alexandria. Two to four brigades, plus a battery of Regular artillery--the best arm against raw infantry--formed a division. In all, thirteen brigades were organized into five divisions. McDowell parceled out his forty-nine guns among his brigade commanders, who in turn attached them to their regiments. His total force for the advance was 35,732 men, but of these one division of 5,752 men dropped off to guard roads to the rear.
McDowell's advance against Beauregard, on four parallel routes, was was hastened by northern opinion, expressed in editorials and Congressional speeches, demanding immediate action. Scott warned Lincoln against undertaking the "On to Richmond" campaign until McDowell's troops had become disciplined units. But Lincoln, eager to use the 90-day militia before they departed, demanded an advance, being aware that the Confederates were also unseasoned and cherishing the belief that one defeat would force the South to quit. Scott, influenced by false intelligence that Beauregard would move immediately on Washington, acceded. Accordingly, McDowell's battle plan and preparations were expedited. The plan, accepted in late June, called for Butler and Patterson to prevent the Confederates facing them from reinforcing Beauregard, while McDowell advanced against Manassas to outflank the southern position. Scott called it a good plan on paper but knew Johnston was capable of frustrating it if given the chance. McDowell's success against the Confederate center depended upon a rapid 30-mile marcli, if 35,000 Federals were to keep 22,000 Confederates from being reinforced.
On July 16, 1861, the largest army ever assembled on the North American continent up to that time advanced slowly on both sides of the Warrenton pike toward Bull Run. McDowell's match orders were good, but the effect was ruined by one unwise caution to the brigade commanders: "It will not be pardonable in any commander . . . to come upon a battery or breastwork without a knowledge of its position." The caution recalled to McDowell's subordinates the currently sensationalized bugbear of the press of being fooled by " masked batteries," a term originating at Sumter where a certain battery was constructed, masked by a house which was demolished just before the guns opened fire. Accordingly, 35,000 men moved just five miles on the 17th. Next day the Federals occupied Centreville, some four miles cast of Stone Bridge, which carried the Warrenton pike over Bull Run.
Beauregard's advanced guards made no effort to delay the Federals, but fell back across the battle line, now extending some three miles along the west bank of Bull Run, which meandered from Stone Bridge southeast until it joined the Occoquan stream. The country was fairly rough, cut by streams, and thickly wooded. It presented formidable obstacles to attacking raw troops, but a fair shelter for equally raw troops on the defensive. On the 18th, while McDowell's main body waited at Centreville for the trains to close up, the leading division demonstrated against Beauregard's right around Mitchell's Ford. The Federal infantry retired after a sharp musketry fight, and a 45-minute artillery duel ensued. It was the first exchange of four standard types of artillery ammunition for all muzzle-loading guns, whether rifled or smoothbore. Solid shot, shell, spherical case or shrapnel, and canister from eight Federal guns firing 415 rounds were answered by seven Confederate pieces returning 310 rounds. Steadily withdrawing its guns, the oldest and best drilled unit of the South, the Washington Light Artillery of New Orleans, broke off the fight against welltrained U.S. Regular artillery. Both sides had used rifled artillery, which greatly increased the accuracy and gave a range more than double that of the smoothbores. Yet rifled guns never supplanted the new, easily loaded Napoleons. In the fight, defective Confederate ammunition fired from three new 3-inch iron rifles would not fly point foremost but tumbled and lost range against McDowell's gunners. That the error went undetected for days reveals the haste in which Davis had procured his ordnance.
Sure that his green troops could not flank the Confederate right, McDowell tarried two more fateful days before he attacked in force. Engineers reconnoitered for an undefended ford north of Stone Bridge. Finding no vedettes at the ford near Sudley Springs, McDowell decided to envelop the Confederate left on July 21 and destroy the Manassas Gap Railroad to keep Johnston from reinforcing the outnumbered Beauregard. The idea was excellent, but the timing was slow.
While McDowell frittered away four and a half days before he was ready to envelop in force, new tools of warfare swung the advantages of mobility, surprise, and mass at critical points toward Beauregard. On July 17 spies in Washington told of McDowell's departure from Alexandria. By electric telegraph Beauregard in turn alerted Richmond. Davis, also telegraphing, ordered commanders around Richmond, at Aquia Creek, and at Winchester to concentrate their available strength at Manassas. Johnston lost no time in deceiving Patterson by using Col. J. E. B. Stuart's cavalry as a screen and adroitly maneuvering his infantry away from the valley. Johnston selected the best overland routes for his artillery and cavalry marches and arranged for railroad officials to move his four infantry brigades. Brig. Gen. Thomas Jackson's lead brigade, accompanied by Johnston himself, covered fifty-seven miles in twenty-five hours by road and rail, reaching Beauregard on the 20th.
At daylight on the 21st, McDowell unmasked the first phase of his attack plan. Three brigades of Brig. Gen. Daniel Tyler's division appeared before Stone Bridge, and a huge, 30-Pounder Parrott rifle dragged into place by ten horses commenced a slow fire, directed by six cannoneers of the 2d U.S. Artillery. Five brigades in two divisions directly under McDowell's command meanwhile marched on an 8-mile circuitous route toward the undefended ford at Sudley Springs. McDowell's goal was the Confederate left rear and a chance to cut the railroad. At 9:00 a.m. a signal flag wigwag from the Henry house announced the point of the enveloping columns at Sudley's crossing, and the intelligence was immediately relayed to Beauregard and Johnston, who were three miles away on the Confederate right.
The first weight of the Federal attack fell against eleven Confederate companies and two guns. For an hour McDowell's regiments, firing one by one and moving forward cautiously in piecemeal fashion, tried to overrun Beauregard's left flank. The timid tactics gave Beauregard time to redeploy ten regiments across a 3-mile front to form a second defensive line across the north face of the hill behind the Henry house. At 10:30 a.m., as the summer sun grew hotter, a portentous dlust cloud, rising ten miles northwest of Manassas, heralded the arrival of Kirby Smith's brigade, the tall of Johnston's reinforcements from the Shenandoah Valley.
For two hours the roar of the battle swelled in volume. Federal musketry crashes and the thunder from the heavier pieces indicated that McDowell was now committing whole brigades, supported by four batteries of artillery. North of the Warrenton turnpike, the Confederate infantry began to lose its brigade cohesion and fall back in disorder. As Beauregard and Johnston rode to the sound of battle, some 10,000 Federals were punishing 7,000 Confederates in the vicinity of the Henry and Robinson houses. Johnston, though senior in command, turned the battle over to Beauregard and galloped off toward Manassas to direct the arrival of reinforcements. Brig. Gen. Barnard E. Bee's brigade was pushed back from its advanced position toward the flat-crested hill behind the Henry house, where Jackson's newly arrived brigade had formed. In rallying his routed troops, Bee shouted: "Look at Jackson's Brigade; it stands like a stone wall! Rally behind the Virginians!" (Out of these words came a nickname that Jackson would carry to his grave, and after his death in 1863 the Confederate War Department officially designated his unit the Stonewall Brigade.) Screened by a wooded area, three brigades regrouped behind Jackson's lines, and the rally became a great equalizer as McDowell's strength dissipated to 9,000 men, with no immediate infantry reserves in sight.
The cloud of dust moved closer to Manassas Junction, but McDowell ignored it and allowed a lull to settle over his front for almost two hours. At 2:00 p.m., having deployed two batteries of Regular artillery directly to his front around the Henry house with insufficient infantry protection, McDowell renewed the battle. By midafternoon the dust had blended sweaty uniforms into a common hue, and more and more cases of mistaken identity were confusing both sides in the smoke of the battle. Then, as part of the confusion, came a fateful episode. To the right front of McDowell's exposed artillery, a line of advancing blue-clad infantry, the 33d Regiment, Virginia Volunteers, suddenly appeared through the smoke. The Federal artillery commander ordered canister, but the chief artillery officer on McDowell's staff overruled the order, claiming that the oncoming blue uniforms belonged to friendly infantry arriving in support. The Virginians advanced to within seventy yards of the Federal guns, leveled their muskets, and let loose. The shock of their volley cut the artillery to shreds, and for the remainder of the day nine Federal guns stood silent, unserved, and helpless between the armies.
About 4:00 p.m., Beauregard, with two additional fresh brigades, advanced his entire line. Shorn of their artillery, the faltering Federal lines soon lost cohesion and began to pull back along the routes they knew; there was more and more confusion as they retired. East of Bull Run, Federal artillery, using Napoleon smoothbores in this initial pullback from the field, proved to the unsuspecting Confederate cavalry, using classic saber-charging tactics, that a determined line of artillerymen could reduce cavalry to dead and sprawling infantry in minutes.
As in so many battles of the Civil War yet to come, there was no organized pursuit in strength to cut the enemy to ribbons while lie fled from the immediate area of the battlefield. At Bull Run the Federal withdrawal turned into a panic-stricken flight about 6:30 p.m., when Cub Run bridge, about a mile west of Centreville, was blocked by overturned wagons. Sunset would fall at 7:15 p.m., and President Davis, just arrived from Richmond, had two daylight hours to arrive at a decision for pursuit. In council with Johnston and Beauregard, Davis instructed the whole Confederate right to advance against the Centreville road, but apparently his orders were never delivered or Beauregard neglected to follow them. Davis thus lost a splendid opportunity for seeing in person whether the unused infantry and artillery on the right of his line could have made a concerted effort to destroy McDowell's fleeing forces. Logistically, Federal booty taken over the next two days by the Confederates would have sustained them for days in an advance against Washington.
Strategically, Bull Run was important to the Confederates only because the center of their Virginia defenses had held. Tactically, the action highlights many of the problems and deficiencies that were typical of the first year of the war. Bull Run was a clash between large, ill-trained bodies of recruits, who were slow in joining battle; masked batteries frightened commanders; plans called for maneuvering the enemy out of position, but attacks were frontal; security principles were disregarded; tactical intelligence was nil; and reconnaissance was poorly executed. Soldiers were overloaded for battle. Neither commander was able to employ his whole force effectively. Of McDowell's 35,000 men, only 18,000 crossed Bull Run and casualties among these, including the missing, numbered about 2,708. Beauregard, with 32,000 men, ordered only 18,000 into action and lost 1,982.
Both commanders rode along the front, often interfering in small unit actions. McDowell led his enveloping column instead of directing all his forces from the rear. Wisely, Johnston left the battlefield and went to the rear to hasten up his Shenandoah Valley reserves. Regiments were committed piecemeal. Infantry failed to protect exposed artillery. Artillery was parceled out under infantry command; only on the retreat was the Union senior artillery officer on the scene allowed to manage his guns. He saved 21 guns of the 49 that McDowell had. Beauregard's orders were oral, vague, and confusing. Some were delivered, others were never followed.
