In January, 1869, F Company of the 61st Foot was moved to Warwick to work on the Military Road (now, the South Shore Road), following which they constructed the rifle ranges at Warwick Camp. Two companies of the 15th Foot continued working on the road, west of Warwick Camp, and also built a new battery for the coastal artillery at Whale Bay (several older forts housing coastal artillery had existed within what became the boundaries of Warwick Camp prior to 1816).
