gliding low over Ford Island, enemy character now positive. This was not a drill." Commencing fire at "any and all planes which passed within a reasonable distance of the nest" Zane began preparations at 0803 for getting underway, as belting and ammunition supply parties turned to. At 0830, Zane spotted a "strange submarine" 200 yards astern of , anchored in nearby berth K-23. Zane's position in the nest, however, rendered her incapable of opening fire with her after 4-inch gun: her aim was fouled by Perry (DMS-17), moored outboard. However, soon made the whole problem academic at 0840, when she charged down upon the Japanese type "A" midget submarine and destroyed her by ramming and with depth charges. Meanwhile, the fleet gradually began to return fire and, by the time the second wave of Japanese planes arrived, the fleet was at action stations. Gunfire from a nearby ship (possibly Medusa) brought down one Japanese plane, whose bomb had burst in the water near Perry. The enemy aircraft exploded into flames on the way down and crashed on shore near the recently completed deperming station to the loud cheers of all hands topside in Zane. Subsequently, the ships of MinDiv 4 got underway individually and stood out to take up patrol offshore. Zane had suffered no damage from the enemy during the raid, but the melee of "friendly" antiaircraft fire from a number of ships nearby, including some in the nest itself, had severed a number of strands of rigging and antennae. At 1410, Zane and Wasmuth rigged up a twin-ship, moored-mine sweep with 400 fathoms of wire between them and entered the Pearl Harbor entrance channel at 1547, sweeping up to the vicinity of the gate vessel before the sweep wire parted. Subsequently, returning to sea, Zane resumed antisubmarine patrols, carrying them out at a time when submarine sightings (most of them fictitious) proliferated. 1942 Zane operated locally out of Pearl Harbor into the spring of 1942. She departed the Hawaiian Islands on 5 April, escorting an convoy (number 4079) to San Pedro, Los Angeles. The high-speed minesweeper then underwent repairs and alterations at the Mare Island Navy Yard before she returned to Pearl Harbor in early June. Meanwhile, the tide of war was beginning to turn. Eight months after Pearl Harbor, the United States Navy was ready to launch its first amphibious operation, codenamed Operation Watchtower. The target was
