The aft 50 calibers sank one barge, but the other caught under the bow of the PT and plugged its escape route. Skipper Dean solved the problem by shoving the throttles up to the stops and riding over the barge, which swamped and sank under the PT’s weight. The 114, once free from the two _daihatsus_, turned back into the inlet with guns roaring. The 129 came running, and the two PTs mopped up the rest of the six-barge convoy. The Australian army had taken on the job of throwing the Japanese out of the three Huon Gulf villages that formed the western hinge of the Japanese gate. They were doing as well as could be expected with the nasty job of fighting in the filthy jungles of New Guinea, but they were having supply problems almost as serious as those of the blockaded Japanese. The Allies had no beachhead near the Australians, and supplies, in miserly quantities, had to be flown to a jungle airstrip and packed to the troops by native bearers. The PT fleet in New Guinea had become so sophisticated by this time that it had acquired a formal organization and an over-all commander, a former submarine skipper named Morton Mumma. Aboard one of his PTs, Commander Mumma had gone poking about the little-known shoreline around the Huon Gulf (Mort Bay was named for him, because he first explored it), and he had found a fine landing beach at Nassau Bay. The beach was right under the nose of the Japanese garrison at Salamaua, it’s true, but it was also temptingly handy to the Australian lines. On the last day of June, 1943, three PTs packed a company of riflemen on their deck. With 36 small Army landing boats, the PTs sortied into a foul sea, lashed by high winds and rain. Total naval escort for the amphibious armada was PT 168, which presumably was in better fighting trim than the others, because it carried no seasick passengers. PT 168 promptly lost its convoy in the storm. _The Flying Shamrock_ (PT 142) missed the landing beach at Nassau Bay and did a countermarch. In the rain and darkness, the _Shamrock_ beat the astronomical odds against such an accident by ramming the tiny PT 143, to the alarm of the miserable foot soldiers on both boats. The Army landing craft scattered in the storm, and the two PTs had to round them up and guide them to the beach, where several broached in the high surf and were abandoned. Short of landing craft to put their own sea-weary passengers ashore, the PTs had to carry them back to the staging area. Despite the less than 100 per cent efficiency of the operation, the few American soldiers who had reached the beach threw the Japanese garrison into a panic. A lucky bomb hit had killed their able commander, and without his support the 300 Japanese assigned to guard Nassau Bay broke and fled before the insignificant Allied invasion force.
