Colonel Charles Coster
Colonel Charles Coster of the 134th New York Infantry Regiment commanded the brigade at Gettysburg as senior colonel. Coster was a 26 year old member of a wealthy mercantile family from New York City. Immediately after Fort Sumter he joined the 7th New York State Militia, one of the first regiments to arrive in the defence of Washington. After that 3 month regiment mustered out he enlisted as a lieutenant in the 12th United States Infantry, where he was commended for his actions at Gaines’s Mill.
Coster was appointed colonel of the 134th New York Volunteer Infantry in October of 1862. The regiment was part of Buschbeck’s Brigade, which stood firm and fought well during the collapse of the 11th Corps at Chancellorsville. Coster temporarily took command of the brigade in June of 1863 when Colonel Buschbeck went on leave. After Gettysburg Coster resigned his command, serving as provost marshal in New York.
