Wilfred J. "Jasper" Holmes (April 4, 1900 – January 7, 1986) was a US Naval officer, one of the Station HYPO staff, who had the idea of faking a water supply failure on Midway Island in 1942. He suggested using an unencrypted emergency warning, in the hope of provoking a Japanese response, thus establishing whether Midway was a target. ==Early years== Born in Stockport, New York, Holmes was the son of Johan Erik Jonasson Holmes, a Finnish immigrant who worked as a fireman in a paper mill, and Esther F. Holmes.〔US Federal Census, 1900〕 Wilfred Holmes graduated from the US Naval Academy, Annapolis, 1922, and had a master's degree in engineering from Columbia University. He served as a line officer in the Navy, in submarines. He wrote submarine adventure stories for the Saturday Evening Post under the pen name Alec Hudson.〔( Jasper Holmes in “Maritime Texas” )〕 He retired from the Navy in 1936 because of arthritis of the spine, and joined the faculty of the University of Hawaii. ==Intelligence Officer== In 1941 Captain Holmes was recalled to duty and assigned to Station HYPO, which was breaking Japanese codes, especially their naval cipher JN-25. By May 1942 US Naval Intelligence knew that the Japanese were planning an attack at a spot they called AF, but did not know what AF signified. Navy cryptanalyst Joseph Rochefort thought AF was Midway Island. Holmes had the idea of faking a water supply failure on Midway. He suggested using an unencrypted emergency warning, in the hope of provoking a Japanese response, thus establishing whether AF was Midway. Holmes’ ruse worked and led to the Japanese defeat at the Battle of Midway. Holmes was awarded the Distinguished Service Medal.〔Michael Smith.
