This is Steve Dunn's story of the Dover Patrol 1914-18. I read a bit about the Dover Patrol when writing my book on HMS Ambuscade because the WW1 destroyer of that name briefly served there. I relied on Admiral Bacon's book The Dover Patrol 1915-17, and the papers and ships' logs in the National Archives and the Greenwich Museum library. I must have missed this 2017 book, or ignored it, as it doesn't mention the ship. Nonetheless, it is a comprehensive study of the Dover Patrol from its inception to the end of the war.
The Dover Patrol formed a discrete unit of the Royal Navy based at Dover and Dunkirk for the duration of the First World War. Its primary task was to prevent enemy German shipping, chiefly submarines, from entering the English Channel en route to the Atlantic Ocean and the allied shipping lanes. Its roles also included protecting the supply and troop transport convoys from Britain to France and bombarding the German positions in Belgium.
In 1914, the bombardment of German positions in Belgium took priority. The ships available to the Patrol were not well-equipped to act as floating artillery, as the Grand Fleet was based in Orkney. Some older battleships, cruisers and monitors were deployed to supplement the period's lightly armed destroyers, but they were vulnerable to German submarines. Once the Germans captured the Belgian ports, they created submarine bases, and losses mounted.
Nearly 81,000 tons of shipping were lost in March 1915, and U-boats were slipping through the Dover Straits at will. This failure led to the dismissal of the first commander, Rear Admiral Horace Hood, although his wanting to sack Churchill's brother-in-law may have been a contributing factor. He was replaced by Vice-Admiral Sir Reginald Bacon, who commanded until early 1918. Various methods were used to create a barrage across the channel, with mixed success. Nets deeper than 40ft rarely survived the Channel tides, and the gaps were plugged with mines. Lots of drifters or small trawlers were used to maintain the barrage, but the Germans frequently found a way through or over the barrage.
Mine warfare was in its infancy, and they often came adrift and sank British ships. The Germans floated their own mines into the Channel to add to losses. By 1917, Bacon had around 20 destroyers, four monitors, six minesweepers and eight submarines, along with auxiliary vessels, but many more were in the dockyards for repairs. Dover was also not an ideal port as a base. By the end of 1917, 39,000 of the newer contact mines had been laid.

The book covers the many naval actions around the barrage, fought mainly by destroyers and submarines. They also bombarded the ports of Zeebrugge and Ostend, followed by the famous raids. These raids were promoted by the last commander, Acting Vice-Admiral Sir Roger Keyes. He divided opinion, with some welcoming his more aggressive tactics, while others thought him self-centred and a trophy hunter. By July 1918, he had 41 ships at his disposal.
The Dover patrol became a jack-of-all-trades. Bacon believed hunting submarines was 'almost useless and hopeless', although the Patrol managed to sink 22. However, the German navy never managed to disrupt the supply chain between Britain and France, and not a single soldier was lost in transit. That included 12 million soldier movements, 2094 troopship movements, and 3875 hospital ship movements. U-boats were forced to travel all around the UK, although the barrage was only fully impenetrable by the summer of 1918. The Patrol lost eight of the 84 destroyers that served there, and 2,000 men died, 6 per cent of all naval losses. These were mostly amateur sailors and fishermen. They are remembered in various memorials, including this one at Dover.
For wargamers, there are many small ship actions that can be refought on the tabletop, particularly using destroyers. Jutland is fine, but it was the only major fleet action, and the naval war in WW1 was really about blockade and the smaller warships.
