Company A was among the companies sent out as skirmishers in the reconnaissance, and was under temporary command of Lieutenant Charles Whittier due to the sickness of Captain Harry Tremlett. Private Oliver Stanton Bates was among the skirmishers in the reconnaissance. Although he did not leave a personal record of the account, he was undoubtedly grateful that the regiment escaped without casualties.1
