More and more as the by-passed Japanese became progressively demoralized by lack of food and rest, the PTs were pressed into service as Black Marias, police vans for carrying Japanese captives from the front lines, or even from behind the lines, to Army headquarters where Intelligence officers interrogated the prisoners.
Most Japanese simply would not be captured, and killed themselves rather than surrender. Many of them made dangerous prisoners, for they surrendered only to get close enough to their captors to kill them with concealed weapons.
On the night of July 7, 1944, Lieut. (jg) William P. Hall, on the 329, dropped a fatal depth charge under a 130-foot lugger south of Cape Oransbari. The crew snagged four prisoners, one of them a lieutenant colonel, one of the highest ranking officers taken prisoner in New Guinea.
One of the prisoners attacked Lieut. Hall, who flattened him with a right to the mouth. Hall sprained his thumb and badly gashed his hand on the prisoner’s teeth. He was awarded the Purple Heart for being wounded “in the face of the enemy.”
Oddly enough, what few Japanese did let themselves be taken made docile, even eagerly cooperative, prisoners. PT crewmen could never tell what was coming on a Black Maria mission. Either the captives tried to kill themselves or their guards—or they tried to help the guards kill their former comrades.
On the night between March 16th and 17th, Lieut. H. M. S. Swift (the Lieut. Swift of the great air battle at Aitape) was out with Lieut. (jg) Eugene E. Klecan’s 367 and 325. Off Pak Island, the two boats caught nine Japanese in a canoe. As the PTs approached, one Japanese killed himself and three others with a grenade. Another was shot by PT sailors when he resisted capture. The others came aboard willingly.
One of the captives asked for a pencil and wrote: “My name is Kamingaga. After finished Ota High School, I worked in a Yokohama army factory as an American spy. I set fire to Yokohama’s arsenal. Later, I was conscripted into the Japanese army, unfortunately. I was very unhappy, but now I am very happy because I was saved by American Army. To repay your kindness I will work as a spy for your American Army.”
He was turned over to skeptical Army officers, who did not make a deal with the traitorous captive.
Another Japanese canary, however, sang a most profitable song to his captors.
On the night between April 28th and 29th, Ensign Francis L. Cappaert, in 370, and Ensign Louis A. Fanget, in 388, sank three barges in Nightingale Bay, east of Wewak.
