In April 1943, Commander Peter Gretton was in charge of escorting a vital Allied trade convoy from New York to Great Britain across the North Atlantic. Over the course of the voyage, the sixty-one merchant ships of convoy HX231, along with the six ships of B7 Escort Group, were continuously shadowed and attacked by a German wolf pack of twenty U-boats.
With the aid of air support, the convoy and defending escort fought valiantly across hundreds of miles of ocean and, despite poor weather conditions, managed to sink and severely damage several enemy submarines. Tragically six merchant ships were torpedoed and with no rescue vessel any survivors were left stranded in the freezing waters of the Atlantic as the convoy continued on its journey.
Drawing on reports from both sides, Gretton details the sequence of events as convoy HX231 battled its way through a large wolf pack and offers an authoritative post-battle analysis of the strategies, decisions, and actions taken that would ultimately see the tide of war turn in favor of victory for the Allies.
Crisis Convoy takes the listener to the heart of the action and is a thrilling account of naval warfare during World War II.
Vice Admiral Sir Peter Gretton's book is a brilliant account of his career in the navy through World War Two: fighting in the Second Battle of the Narvik and guarding convoys in the Mediterranean and the North Atlantic, before being placed in charge of Escort Group B7, which he described as 'the finest job in the Navy for a new commander.' It was in this role that Gretton, and the seven warships under his command, were able to make their contribution to turning the tide against the U-boat threat.
On April 22, 1943, Gretton was in charge of the escort for Convoy ONS 5 during its journey across the North Atlantic. Over the course of the voyage they were attacked by over fifty U-boats, and although they lost thirteen ships they managed to sink six U-boats and seriously damage many more. The U-boats had never faced such fierce resistance to their lethal raids. What tactics had Gretton used to fend off Doenitz's terrifying submarine wolf packs? And how had these strategies developed over the course of the war?
Convoy Escort Commander demonstrates how Allied commanders searched for new methods to repel U-boat assaults, including using direction-finding radio and radar, employing special tactical formations, coordinating with air cover, and endeavoring to keep the convoy together and prevent straggling.
