On 19 May, 1918, the convoy of chasers left Gibraltar for Malta, the next stop along their way to Base 25, Corfu. Ens. George S. Dole, CO of submarine chaser SC 93, writes in a letter home, "Am over there now. ... I would not swap my job for any on earth. Will be into it long before you get this letter, and WE ARE GOING TO GET THEM."

Author's note: This is one of my favorite WWI chaser photos, showing the scale of the submarine chaser moving along with the tanker, against the stunning background of Gibraltar.
