 Warwick Camp continued to be used by all units in its training role, but also housed Territorial infantry units that had been embodied for the duration of the war.Prior to the December, 1941, entry of the United States into the war, the United States Army and the United States Marines Corps were permitted to deploy forces to Bermuda, ostensibly to guard base sites to which the United States had been granted leases by the British Government, but with the intent of also allowing the neutral US to covertly reinforce the colony's defences.Among the American units deployed to Bermuda was a battery of two 155mm GPF artillery guns ("B" Battery, 57th Regiment, United States Army Coast Artillery Corps) deployed to "Ackermann's Hill", on the northern side of the South Shore Road (behind Horseshoe Bay), in Southampton Parish (this part of Warwick Camp was disposed of after the war and has now been densely built-up with private housing).
