J.C. Truesdale, Chaplain of the 105th Pennsylvania Infantry, is buried in Big Woods Cemetery in Eola, Illinois. I found a wonderful history of this unit, which says (in part) ” The 105th was raised mainly in the counties of Jefferson, Clarion and Clearfield; was organized at Pittsburg in Sept. and Oct., 1861, and mustered into the U. S. service for a three years, term. It was ordered to Washington in October and assigned to the 1st brigade, 1st division, 3rd corps, in camp near Alexandria. Leaving camp on March 17, 1862, the regiment took part in the siege of Yorktown and the battles of Williamsburg and Fair Oaks.”
I also found a Wikipedia article about this regiment, which says “The 105th Pennsylvania Volunteer Infantry, also known as the “Wildcat Regiment” was an infantry regiment that served in the Union Army during the American Civil War.”
Looking a bit more, I found reference to Reverend J.C. Truesdale in a book, History of Jefferson County, PA, which says, “The next pastorate was that of Rev. J.C. Truesdale. About the year 1859 this brother took charge of Jefferson. His pastorage was short, covering a period of about four years, but it was interesting. The anti-slavery controversy grew warm. Civil war was inaugerated. They took sides as they were loyal or disloyal, and as this brother uttered no uncertain sounds, he was highly esteemed, and he was cordially hated. Some time during the year 1863 he resigned his pastoral charge and and entered the army as a chaplain. In this he served to the close of the war.” This book goes on to mention that Reverend Truesdale settled, after the war, in a Presbyterian congregation in Paxton, Illinois for a few years. Paxton, IL is about 2 hours away from Eola, IL, where this marker is.
