|Brigadier General James Nagle|
His resignation was accepted, but not without the regret from his superiors. On May 9, Samuel Sturgis, commander of the Second Divison, 9th Corps, forwarded Nagle's resignation, but took the time to write the following back to the suffering Nagle: Dear General: I cannot better express the pain it gave me to forward your resignation, than by giving you a copy of my endorsement upon it, viz.: 'Respectfully forwarded and approved. But I must express my deep regret at the necessity for this forwarding it. By his intelligence, energy, zeal and courage, and quiet, unassuming deportment, withal, Gen. Nagle has endeared himself to this command, and will carry with him the love and respect, not only of those gallant troops he had led so often to victory, but of all who have the good fortune to know him."
His resignation accepted and approved, Nagle said goodbye to his men on May 20 and issued his farewell address:
With that, Nagle boarded a traincar and was soon heading back home to his family in Pottsville, Pennsylvania. Yet no sooner had he arrived than Robert E. Lee led his Army of Northern Virginia in his second invasion of Union soil, this time making it deep into Nagle's home state of Pennsylvania. Heralding the call once more, Nagle, despite his poor health, set about raising yet another regiment of volunteers--the 39th Pennsylvania Emergency Militia--which he would lead to the front. Arriving in Harrisburg during the latter stages of the Gettysburg Campaign, Nagle was assigned brigade command by General Darius Couch, who headed the Department of the Susquehanna.
