guerrillas. Along with her passengers, Crevalle recovered a group of important documents (the Japanese "Z plan"), and transferred all she could spare in the way of supplies to the guerrillas. In May 1944, while returning with her passengers to Darwin, Crevalle was spotted by a Japanese convoy on the third day of the journey. With four working torpedoes Capt. Walker maneuvered to attack, but was severely depth-charged by a Japanese bomber, a special ordeal for the passengers. The periscopes and radar were knocked out. They were landed safely at Darwin 19 May, 8 days after leaving the Philippines. Most uniquely, one of the female passengers also gave birth to a healthy baby boy during the return trip. Crevalle sailed on to refit at Fremantle. For her fourth war patrol, Crevalle returned to the South China Sea, as well as cruising off the northern Philippines, between 21 June and 9 August 1944. In company with three other submarines for most of this patrol, Crevalle joined in a 30-hour pursuit and attack on a convoy on 25 July and 26 July, damaging one freighter Tosan Maru, and sinking the freighter "Aki Maru" already crippled by one of her groups. Two days later, Crevalle sank another freighter "Hakubasan Maru". Fifth war patrol, September 1944 Refitted once more at Fremantle, Crevalle put to sea on her fifth war patrol 1 September 1944. Ten days later, she surfaced after a routine trim dive. A lookout, Bill Fritchen, was first through the hatch followed closely by the Officer of the Deck, Lt. Howard James Blind. Fifteen seconds later, the boat took a sharp down angle, and submerged with the upper and lower conning tower hatches open, washing the lookout overboard. The flow of water through the upper hatch, which was latched opened, prevented anyone in the conning tower from closing it. The lower hatch to the control was blocked by a piece of floor matting. At the hatch was seen to close and lock. The ship continued diving to at an angle that reached 42 degrees down. With communications out, an alert machinist's mate, Robert L. Yeager, saved the submarine by backing full without orders. The pump room, control room and conning tower flooded completely, and all electrical equipment was inoperative. Yeager received the Silver Star for his action. Bringing the submarine under control, her men surfaced and were able to recover the lookout, but not
