The officers' quarters were used as both a living quarters and the administrative office of the fort. Some of the officers were Major Robert Cluggage, Capt. Thomas Cluggage, Capt. John Lane, Capt. John MacDonald, Capt. Henery Black, and Lt. Robert Gaibraith. Under the Militia Law of March 1777, the men elected all officers in each frontier county's battalion. Colonels, Lt. Colonels, and Majors were required to be resident freeholders within the battalion's district, while company grade officers were selected from the voters.
Officers used various methods to enlist volunteers in their companies. Usually, enlistees were offered a bounty for enlisting in addition to their regular monthly pay. In 1779, the bounty was a suit of clothes. 1n 1778, Thomas Cluggage's company received a bounty of sixty dollars. Volunteers were also recruited by promises of land grants after the war.
The Cluggage brothers were from Black Log Valley (now southern Huntington County). Major Robert Cluggage was the District Justice for this area prior to the war. He was active in military service from the beginning of the Revolution. He commanded a company of Thompson's Rifle Battalion during the siege of Boston. He returned to his home in Black Log Valley, and then served as a major at Fort Roberdeau from 1778 to 1781 in command of local militia and three ranging companies.
