North Sea After the outbreak of war in September 1939,
Warspite was assigned to the
Home Fleet. Due to the lack of anti-submarine precautions at the
North Sea naval bases, it was some time before she reached
Scapa Flow, the main fleet anchorage. Until the start of the
Norwegian campaign on 9 April 1940, action had been severely limited by the
U-boat threat. A significant German naval presence in the North Sea saw the Home Fleet off the coast of Norway. The inconclusive
first battle of Narvik was on 10 April. On 13 April, Crutchley commanded
Warspite in the
second battle of Narvik. She accompanied nine destroyers into
Ofotfjord, where eight German destroyers were sunk or scuttled.
Warspites catapult plane even sank a U-boat. After this action, Crutchley was appointed commodore of
Royal Naval Barracks, Devonport, overseeing the preparation of crews for assignment to ships. While there he was greeted by a detachment of sailors who had served on
Warspite at Narvik:
South West Pacific Area After the opening of hostilities with
Japan, Crutchley was promoted to rear admiral and lent to the
Royal Australian Navy for service in the
South West Pacific Area. On 13 June 1942 Crutchley succeeded Rear Admiral
John Crace in command of
Task Force 44, the Australian Squadron, based in
Brisbane, the last Briton to do so.
Battle of Savo Island During the landings on
Guadalcanal, on 7 August 1942, Crutchley served as Commander Task Group 62.2 (CTG 62.2), the covering group, with his flag in . TG 62.2 included three Australian and five
American cruisers, fifteen destroyers, and some minesweepers. He was under Admiral
Richmond K. Turner of the
United States Navy, commander of the amphibious force. TG 62.2 was on constant alert, rendering support to the landings or fending off Japanese air attacks. On 8 August, Vice Admiral
Frank Jack Fletcher withdrew the
aircraft carriers that had provided air cover. Turner decided the amphibious force must also leave the next day. He summoned Crutchley and Major General
Alexander Vandegrift (commander of the troops on Guadalcanal) to an evening conference on his flagship. Crutchley took
Australia to the amphibious anchorage, leaving five cruisers and six destroyers on guard to the west. That night a powerful Japanese cruiser force attacked. They caught Task Group 62.2 by surprise, and sank four Allied cruisers, including . In the wake of the disaster, Crutchley was heavily criticised, both for leaving his command, and for an ineffective deployment which allowed the Japanese to get close without being detected by
radar. Crutchley nonetheless retained the confidence of his superiors. He remained with the RAN in the South West Pacific, commanding TF 44 (redesignated TF 74 in 1943) for another 23 months. His command of the Australian Squadron ended on 13 June 1944. In September 1944, Crutchley received the American
Legion of Merit in the degree of Chief Commander. ==Later years==
