Order of Battle


By the summer of 1862 the armies of both sides were beginning to develop corps headquarters to control the divisions assigned to them. In June 1862 General Lee divided his army into "wings" under Jackson and Longstreet, respectively. These were organized formally into corps in November of that year. An informal corps organization had existed among the Federal forces since late 1861. These were formally designated in July 1862, but first were numbered sequentially within their respective field armies, causing some confusion. Many of the corps were still forming at the time of the Second Manassas Campaign, hence they were not much better structured or coordinated than their Southern counterparts. There were usually two or three divisions in each corps, sometimes more. Normally three, occasionally four, brigades composed a division. Four or five regiments were assigned to a brigade.

Various manpower practices, plus battle losses, make it extremely difficult to calculate strength accurately by unit designation alone. Volunteer infantry regiments were composed of ten companies, each authorized a maximum of 101 officers and men. With staff included, a full regiment would have numbered about 1,025 officers and men. Regular U.S. Army Infantry regiments were organized into three battalions of three companies each and Federal heavy artillery regiments converted to infantry had three four-company battalions. As a result, they were slightly larger than the volunteer regiments. Federal regiments at Second Manassas had an average strength of 300 men, while similar Confederate units averaged 200 men.

Artillery batteries on the Federal side generally were standardized with six M1857 12-pounder Napoleon pieces. There were about 100 men in a full strength Federal battery. Confederate batteries, on the other hand, ranged from six to two pieces and usually had various models of guns grouped together. This lack of uniformity was offset by a much better higher-level structure. Most Confederate artillery was grouped in battalions deployed under the orders of the wing commander. This arrangement allowed greater firepower to be brought to bear more responsively than on the Federal side. There, batteries were assigned to division, even brigade, levels, often operating independently once battle was joined. The Federals had 38 batteries with 182 guns at Second Manassas, while the Confederates had 184 guns grouped in 45 batteries.

The dissimilarities in centralization extended also to the cavalry. Confederate horse was organized in a single cavalry division, responsive to the needs of the army commander. It was used primarily to gather information. Federal practice assigned cavalry to corps and sometimes to as low as brigades. This deprived the army commander of any reconnaissance capability of his own. There was the probability, realized in the 1862 Campaign, that information would not get to him. This shortcoming was made worse by General Pope's philosophy of cavalry use. He caused his subordinates to push the cavalry mercilessly in deep raids and as hard-riding escorts and headquarters guards. Rarely was cavalry used by the Federals solely to obtain information. As a consequence, Pope frequently lost contact during critical changes, fatally hampering his planning. At the same time, the cavalry became so debilitated it could not be a factor when it was needed the most at the climax of the campaign.
