Calvin Brown was a 27-year-old farmer in Palmyra, Maine, when he enlisted in the 1st Maine at Skowhegan in October 1861.
He joined Co. H as one of its two wagoners or teamsters. Wagoners did not ride the wagon, they rode the "saddle horse," the rear, nearside horse in the four-horse team.
They controlled and directed the lead horse in front of them with a single rein and voice commands, and the offside pair worked in tandem.
Without looking at his service records in the National Archives, it's not clear how long Brown served with the regiment's train of wagons.
However, he must have become increasingly disable for field service because he was reassigned to the Veteran Reserve Corps on November 1, 1863.
