Max Horton's Top 3 Tactical Masterpieces | The Man Who Broke the U-Boats

Max Horton took command of the Battle of the Atlantic in November 1942 and within eleven weeks turned forty-one German U-boats sinking in a single month from impossible to routine. Horton inherited convoy escorts spread too thin to both guard merchantmen and hunt submarines, so he fought the Admiralty for support groups — fast warships attached to no convoy that could close on a contact and stay until the target was destroyed. He expanded the tactical school at Liverpool and added live submarine training at Larne so escort commanders reached the Atlantic already worked up. He pressed for long-range aircraft to close the mid-Atlantic air gap where most convoy disasters occurred, and once Coastal Command received Very Long Range Liberators in spring 1943, he used high-frequency direction finding to vector them onto U-boats the moment they transmitted. The three moves followed one pattern: build a second force so guarding and hunting stop competing, cover the space nobody else watches, and turn the enemy's routine into the method that locates him.
