Pennsylvania Regiments at the Seven Days Battles – Corps & Generals

Posted By on April 20, 2011

The Seven Days Battles, occurring from 25 June 1862 to 1 Jul 1862, resulted in a retreat of Union forces away from the Confederate capital of Richmond and down the Virginia peninsula.  The Union Army was headed by Maj. Gen. George B. McClellan and the Confederate Army by Gen. Robert E. Lee.  Battles took place at Oak Grove, Gaines’ Mill, Garnett’s and Golding’s Farm, Savage’s Station, and Harrison’s Landing on the James River.  The final battles were at Glendale, where poorly executed orders from Lee led to Union forces retreating to strong defensive positions, and at Malvern Hill, where Lee’s forces suffered heavy casualties in failed frontal assaults against McClellan’s artillery and infantry.  McClellan ended up in safe positions along the James River, but the Union Army had nearly 16,000 casualties as a result of the seven days of fighting; Lee lost more than 20,000 men.  Lee correctly guessed that McClellan would not again press forward against Richmond and he began preparing his army to move north into northern Virginia and Maryland.

Many men from the Lykens Valley area participated in the Seven Days Battles.  Most would have served with the Pennsylvania regiments who were part of the several army corps that made up McClellan’s forces.  Some served with regiments from other states or served with regular army forces, but those will not be discussed in this post. To help identify those Pennsylvania regiments and the generals who commanded them, the following extract from the “Order of Battle” is presented:

  1. Bill Schoenfeld says:

    Trying to find out information about 3rd PA Reserves at Gaines Mill. My ancestor was the Orderly Sgt for Company C and was mortally wounded. I cannot find any company reports and the regimental report is very limited.

    My ancestor’s name was Thomas P. Goheen.

    Thank you,
