The Dover Patrol Monument is a war memorial designed by Sir Aston Webb to commemorate the Royal Navy's Dover Patrol of the First World War. Two identical granite memorial obelisks, 75 feet (23 m) high, were erected near Dover and Calais in 1921 and 1922. A third was erected in Brooklyn, New York, in 1931. The UK monument became a Grade II listed building in August 1966, promoted to Grade II* in August 2015.
The Dover Patrol was formed in July 1914, around a nucleus of the 12 Tribal class destroyers. Through the First World War, a variety of craft served in the patrol—cruisers, destroyers old and new, submarines, mine-sweepers, armed trawlers and drifters, armed yachts, motor launches and other coastal craft—as well as a variety of aircraft - flying boats, aeroplanes, and airships. From time to time, French destroyers were included in the patrol.
The patrol covered the southern part of the North Sea and the eastern portion of the English Channel, including the Straits of Dover. Its duties included escorting merchant ships, hospital ships and troop transports; anti-submarine patrols; sweeping for German mines, and laying British minefields and anti-submarine nets; and bombarding German land forces on the coast of Belgium and northern France. It was commanded by Admiral Reginald Bacon from 1914 until his retirement at the end of 1917, and then by Vice-Admiral Roger Keyes. Six members of the patrol were awarded the Victoria Cross in a single action on 22–23 April 1918, for their part in the Zeebrugge Raid to block the entrance to the port of Bruges-Zeebrugge and so prevent German vessels from leaving port.
