|CAPT Ashworth presents RADM Showers with his certificate||.|
Less than a year prior to the Battle of Midway, retired Rear Admiral Donald "Mac" Showers had been commissioned on Sept. 12, 1941 as an Ensign. Soon after his commissioning, he received orders to join Pearl Harbor's code breakers. One of very few code breakers, "Mac" was assigned to Station Hypo. Commander Joseph John Rochefort was the Station Hypo officer in charge. Rochefort hand-picked many of Hypo's augmentees, and it contained the Navy's best cryptologists, cryptanalysts, traffic analysts, and linguists. By the spring of 1942, Rochefort's staff, which included Showers, was making positive strides toward deciphering the Japanese Navy's crucial next move.
