reconnoisance outside the picket line to the bank of the river; and at the request of his superior, he dismounted, jumped into the river, and waded across the stream—the object being to ascertain the depth of the water, which in some places came nearly up to his shoulders. On reaching the opposite bank he examined the ground for some distance, and discovered, unseen by them, the position of the enemy's pickets. Barnard reported to McClellan that the river was fordable, and how he had ascertained that it was so. McClellan sent for Custer, and was so pleased with his appearance and courageous act that he transferred him to his own staff; and in June, Custer received from the Secretary of War his appointment as additional aid-de-camp, with the rank of captain during the pleasure of the President. Previously to this he had crossed the Chickahominy at daybreak with a company of infantry, attacked the enemy's picket post, and captured prisoners and arms.
Custer served on McClellan's staff through all of the Peninsular campaign; and after the battles of Gaines' Mills, Fair Oaks, Malvern Hill, etc., retreated with him to the protection of the gunboats at Harrison's Landing on the James River. Subsequently, after the withdrawal of the army from the Peninsula and the defeat of Banks and Pope in Virginia, he was McClellan's aid-de-camp in the Maryland campaign which closed with the battle of Antietam. When McClellan was superseded by Burnside, Nov. 10th, 1862, Custer accompanied his chief to Washington, and subsequently visited his friends in Ohio and Michigan. His staff position as captain ceased with the retirement of McClellan, and he was now a first lieutenant, commissioned July 17th, 1862.
