“I do not think much can be expected of them": John Reynolds and the Pennsylvania Militia in the Maryland Campaign

On the morning of September 17, 1862, two brigades of the Pennsylvania Reserve division anxiously gripped their muskets and rifles behind the northern fence of D. R. Miller’s cornfield. Hordes of panicked Union soldiers passed through their ranks. Confederate flags bobbed above the battle smoke, heading their way. The Rebel yell amplified. Suddenly, these Pennsylvanians, with their backs to their home state, found themselves in the middle of America’s bloodiest single day. 

“I tell you the old cannon balls flew around my head worse than the devil and the musket balls went zip zip around my ears,” wrote Private Sylvester Hower. “I thought they would take me, but they all missed me.”(1) Many Confederate shots found their marks in the Pennsylvanians. By the campaign’s end, the division lost 965 between South Mountain and Antietam.

Even before those battles, the division suffered one of its greatest losses during the campaign: its commander, Brigadier General John Reynolds. The Confederate movement into Pennsylvania in early September 1862 sparked widespread fear among Pennsylvanians that their state would be the next to “welcome” the heels of Robert E. Lee’s Army of Northern Virginia. “Our homes were threatened—the horrors of desolating war seemed likely to be brought to our very doors,” said Lewis Richards.(2) To protect his state and its people, Governor Andrew Curtin called for the state’s men to enroll in local militia outfits and to rendezvous at Harrisburg before being sent to the Maryland-Pennsylvania border to repel the invader.

Curtin continually alerted the authorities in Washington about the information his ring of spies and scouts gathered. He hoped to get something in exchange for his state’s dedication to the Federal war effort: veteran soldiers from the Army of the Potomac to come to the state’s aid. President Abraham Lincoln refused. Curtin and other prominent Pennsylvanians settled for a consolation prize: a competent officer–a Pennsylvanian–to lead the Keystone State’s defense. On September 12, 1862, Curtin got his wish. General-in-Chief Henry Halleck ordered Reynolds to report to Harrisburg. Despite objections from army commander George B. McClellan and Reynolds’ corps commander Joseph Hooker, they did not defy Halleck’s decision and Curtin’s panic. Reynolds would go.

Inspecting the Third Brigade of the Pennsylvania Reserves in the Field of the Maryland Campaign

     In an army of units that saw heavy fighting since the beginning of the Seven Days, fewer Federal divisions suffered worse than the Pennsylvania Reserve Division under the command of John Reynolds. Total casualties during the Seven Days' Campaign total approximately 2,600 men. Another 610 names joined the list at Second Bull Run in late August. On the eve of the Maryland Campaign, the division was a shell of itself.(1)

     While researching in the National Archives today, I stumbled on this incredible inspection report of the division's 3rd Brigade, commanded by Lt. Col. Robert Anderson at the Battle of Antietam. It gives a good glimpse into the state of the brigade, and the division as a whole, on the eve of the battles of South Mountain and Antietam.
