Collection in Context

The Royal Navy Patrol Service (RNPS) was a branch of the Royal Navy which operated during both World Wars. Unlike other branches of the military, the RNPS has roots in the fishing industry. Officers in the RNPS were often recruits from the Royal Naval Reserve who started as fishermen during peacetime. Trawlers, a type of boat that operates by dragging fishing nets across the bottom of the sea, were found to be useful in minesweeping and anti-submarine operations. The small boats primarily worked on the homefront to keep supply lines clear of mines, however; the RNPS was also involved in convoy missions everywhere from the Arctic Sea to the Mediterranean.

The original collection was created by the Ministry of Food and is currently held at the Imperial War Museum. The images in this collection were created from microfilm held at The National Archives.
