Lieutenant John Davies, RNVR, was born in Hertfordshire, England, in 1913 and graduated from the University of London. Before the outbreak of World War II, he taught in England and traveled fairly extensively in Europe. In 1941, he joined the Royal Naval Volunteer Reserve, and, like all officer candidates, received a good part of his training as one of the crew on the lower deck (or, in American terms, as an Apprentice Seaman). This period he spent on a destroyer in the Mediterranean in the critical early months of 1942, when England almost lost Malta, and his ship was sunk by enemy shore batteries in the Eastern Mediterranean. Thus, he became intimately acquainted alike with seasickness and with Axis bombs.
In 1942, Lieutenant Davies won his commission, and early in 1943, came to Washington as a technical officer attached to the British Admiralty delegation.
