An additional 16 men were missing. It was here that Brig. Gen. Henry Bohlen was killed. Colonel Schimmelfennig was eventually promoted to take his place. In the following days, the regiment participated in the battles of Sulphur Springs and Waterloo Bridge before joining the Army of the Potomac for the Northern Virginia Campaign. It participated in heated fighting at Second Bull Run. When the regiment returned to the Washington D.C. area, its command changed. Maj. Adolph von Hartung was promoted to colonel and commander of the regiment, which was stationed near Stafford Court House. There, some of its men who took ill were treated at the XI Corps Reserve Hospital in Fairfax, Virginia. (Today this historic building, complete with Union soldier graffiti on the walls, is known as Blenheim House. Four members of the 74th wrote on the walls of this house.) 1863 service During the early stages of the Battle of Chancellorsville in May, the 74th was among the XI Corps troops that were surprised in camp by the furious flank attack of Jackson's Corps. Another retreat occurred at Gettysburg, where the regiment was pushed through the streets to Cemetery Hill when the brigade retired. Of 381 officers and men, the 74th lost 10 killed, 40 wounded, 60 captured or missing. With the rest of Schimmelfennig's depleted brigade, soon after Gettysburg, the 74th was permanently transferred from the Army of the Potomac to South Carolina, where it saw action in several fights in the swamplands during operations to take Charleston. Battle of Gettysburg The 74th Pennsylvanian Volunteer Regiment saw its most notable battle at Gettysburg where it would lose most of its men, be routed, and have a commander found guilty of cowardice. On the first day of the battle, the regiment was deployed to the front lines and fought until 2 p.m.. The then Colonel of the Regiment, Colonel Adolph von Hartung, who was also a former Prussian Army officer, was wounded the first day. Command of the regiment fell to Lieutenant Colonel Alexander Theobald von Mitzel. The Lieutenant Colonel would be captured by the Confederates during the retreat through the town. When the regiment reorganized itself, command was taken up by Captain Henry Krauseneck.
