First Sergeant William C. Thompson, of Forest, Mississippi, kept things lively for the first few months with his little whistle, followed by the command, "Outside!" Merrill C. Liebensberger, of Hazleton, Penna., served as the first supply sergeant of the battery. David B. Koenig, also of Hazleton, Penna., ranking first as corporal and later as sergeant, was kept busy with office work, acting in the capacity of battery clerk. Lloyd E. Brown, of East Richmond, Indiana, served as the first instrument sergeant of the battery. John M. Harman, of Hazleton, Penna., was the first signal-sergeant to be appointed. It might be remarked in passing that Messrs. Thompson, Liebensberger, and Harman were destined for leadership rank. Before the outfit sailed for overseas all three had gained application to officers' training schools, and were, in the course of time, commissioned as lieutenants. Battery Clerk Koenig continued to serve the outfit in an efficient manner throughout its sojourn in France. Instrument-Sergeant Brown early in 1918 answered a call for volunteers to go to France with a tank corps. While serving abroad he succumbed to an attack of pneumonia and his body occupies a hero's resting place in foreign soil. A wonderful spirit was manifested in the affairs of Battery D despite the fact that the constant transfer of men greatly hampered the work of assembling and training a complete battery for active service in France. Men who spent weeks in mastering the fundamentals of the soldier regulations were taken from the organization, to be replaced by civilians, whereby the training had to start from the beginning. This caused many changes in plans, systems, and policies. Rejections were also made for physical disabilities. For the greater part of the Camp Meade history of the battery, the organization lacked sufficient men to perform all the detail work. Thus days and days passed without any military instruction being imparted. Instruction in army signalling by wigwag and semaphore was started whenever a squad or two could be spared from the routine of detail. Then followed instruction on folding horse blankets, of care of horses and harness, and lessons in equitation, carried out on barrels and logs. Stables and corrals were in the course of construction. By the time snow made its appearance in November horses were received, also more detail. First lessons in the duties of gun-crews and driving squads were also attempted. Materiel was a minus quantity for a long time, wooden imitations sufficing for guns until several 3.2's were procured for the regiment. Later on the regiment was furnished with five 3-inch U. S. field pieces. Training then assumed more definite form. For weeks and weeks the gun crews trained without any prospects of ever getting ammunition and firing actual salvos.
