Sepia-toned image of a young man in a United States Navy uniform from World War I. The banner on his sailor cap states he served on the armored cruiser USS San Diego. Pulled from the Pacific fleet and assigned to escort merchant ships through the North Atlantic with the entry of the U. S. into World War I, the San Diego was struck by a German mine off the coast of New York States on July 19, 1918, sinking less than thirty minutes later, the only major U. S. warship to be lost in the first World War. Though born in Tillamook, Hawke's father, C. E. Hawke, was a physician with a general practice in Forest Grove.
