About Percy W. Nelles

Lived 1892 – 1951 (aged 59). Percy W. Nelles was a Canadian flag officer.

Admiral Percy Walker Nelles, (7 January 1892 – 13 July 1951) was a flag officer in the Royal Canadian Navy (RCN) and the Chief of the Naval Staff from 1 January 1934 to 15 January 1944. He oversaw the massive wartime expansion of the RCN and the transformation of Canada into a major player in the Battle of the Atlantic. During his tenure U-boats raided the Gulf of St. Lawrence, Canadian Northwest Atlantic command was created, and the RCN provided up to 40% of all escort forces in the North Atlantic. His handling of the RCN's war effort had its opponents however, and he was removed from his post as Chief of the Naval Staff in January 1944. He was sent to London as Overseas Naval Attaché, coordinating RCN operations for Operation Overlord. He retired in January 1945 as a full admiral.

Early life Nelles was born in Brantford, Ontario, on 7 January 1892, the son of Brigadier General Charles Mecklan Nelles, CMG (1865–1936) and great-great grandson of Col. Robert Nelles. As a child, Nelles attended the private schools Lakefield Preparatory School and then Trinity College School in Port Hope. As a child he was known to play with boats on the Grand River and wanted to be a part of the navy all of his life. Brigadier General Nelles wrote to the Minister of Marine and Fisheries for an appointment for Percy in the future Canadian naval service.

Nelles returned to Canada in 1931, reverting to the rank of commander. The college was to be similar to the Britannia Royal Naval College at Dartmouth and to the former RNCC. In 1940, Angus Lewis Macdonald explained to the House of Commons "it will be a proud day for this country, when our Canadian naval effort will be directed by Canadian men, trained in Canada and operating in ships built in this country."

In the 1943 New Year Honours, King George VI appointed Nelles as a Companion of the Order of the Bath. Rather than being publicly dismissed from duty, Nelles was transferred to Great Britain and given the nominal post of Senior Canadian Flag Officer Overseas (SCFO(O)), a largely administrative position with little involvement in naval operations. Additionally, the barracks at Naden, CFB Esquimalt, is named in his honour, called Nelles Block. Cadets at Royal Roads Military College were awarded the Nelles Trophy for athletics (running).
