Camp
Camp, the place where an army halts and pitches its tents. The Roman camps used to be square, with entrenchments all round and a gate at each side. Different parts of the camp were the Fossa, the Vallum, the Principia, and the Quintana (all of which see). A camp of instruction is a camp formed in time of peace to instruct and discipline soldiers. A flying camp is one occupied for a very short time.
