Taken from the account of George M. Battey, Jr., who served on the U.S.S. Reid during World War I and spent nine weeks in the Azores (31 July-7 October 1917).
A series of volcanic islands located about 850 miles from Portugal, the Azores proved a valuable stopping point for ships crossing the Atlantic during World War I. Fearing that the Germans would seize the islands to use as a submarine base, the Allies maintained an aeronautic Marine detachment and several anti-submarine craft there.
