The company was marching from Melville Barracks to the Royal Naval Barracks, Chatham, to attend a boxing tournament. It was divided into three platoons; the rear platoon consisted of new recruits who had not yet received uniforms. They were generally under the command of cadet non-commissioned officers (NCOs); the only adult present was the contingent adjutant, Lieutenant Clarence Murrayfield Carter, a regular Royal Marines officer. The column was about fifteen yards long and was marching three abreast on the left-hand side of the road. It was showing no lights, there being no official requirement to do so, and the boys in uniform were wearing Royal Marines standard-issue dark blue battledress and berets, although they had white belts and white lanyards on their shoulders.
