Mosquitos!

80 years ago today: PT boat No. 285 underway, 19 October 1943. Note the extensive camouflage paint scheme on the 78-foot Higgins Motor Torpedo Boat, her SO type radar set, four lightweight Mark 13 aircraft torpedos in roll-off mounts, two twin M2 .50 cal Brownings pointed skyward, another pair of 20mm Oerlikon singles fore and aft, and a 7×3-foot balsa float on deck filled with supplies.

Carrying the unofficial names of “Scuttlebutt John” and “Fighting Irish,” PT-285 was laid down 8 February 1943 by Higgins Industries in New Orleans, completed 16 July 1943, and assigned to Motor Torpedo Boat Squadron TWENTY THREE (MTBRon 23), going on to see action at Bougainville and Green Island as well as in New Guinea, ending her career in the Philippines, stripped and torched off Samar as excess equipment in November 1946.

PT boat No. 337, an 80-foot Elco Motor Torpedo Boat, was photographed the same day in likely the same location, and she gives a great profile view of such a craft. She carries the same torpedo punch as PT-285 above, but one fewer 20mm mount and a wooden dingy instead of the balsa float.

PT-337 was laid down at Elco in Bayonne, New Jersey on 17 February 1943 and completed on 14 May then was assigned to MTBRon 24 for service in New Guinea. Serving under the unofficial names of “Heaven Can Wait” and “PT Intrepid” she was lost to Japanese shore batteries on 7 March 1944 in Hansa Bay, New Guinea.

Bulkely covers the tragic tale in his At Close Quarters book on PT boat operations in WWII:

On the night of March 1/2, Lt. R. H. Miller, USNR, in PT 335 (Lt. Bernard C. Denvir, USNR), with PT 343 (Ens. Fred L. Jacobson, USNR), destroyed two enemy luggers and set fire to a storehouse, a fuel dump, and an ammunition dump at Bogia Harbor, 125 miles northwest of Saidor. On the following night, Lieutenant Commander Davis, in PT 338 (Lt. (jg.) Carl T. Gleason), with PT 337 (Ens. Henry W. Cutter, USNR), went 10 miles farther up the coast to Hansa Bay, a known enemy strongpoint.

The boats idled into the bay at 0200, the 338 leading. They picked up a radar target a mile and a quarter ahead, close to shore. Closing to 400 yards, they saw two heavily camouflaged luggers moored together. Heavy machine-gun fire opened from the beach. As the PT’s turned and started to strafe the beach, more machine-guns started firing along the shore, and a heavy-caliber battery opened from Awar Point, at the northwestern entrance of the bay.

The first shell hit so close to the port bow of the 337 that some of the crew were splashed with water and heard fragments whizzing overhead. Three or four more shells dropped near the 337; then one hit the tank compartment just below the port turret, going through the engineroom. All engines were knocked out and the tanks burst into flame. Ensign Cutter pulled the carbon dioxide release, but the blaze already was too furious to be checked.

Francis C. Watson, MoMM3c, USNR, who had been thrown from the port turret, got to his feet and saw William Daley, Jr., MoMM1c, USNR, staggering out of the flaming engineroom, badly wounded in the neck and jaw. Watson guided Daley forward, slipped to the deck and shouted to Morgan J.

–224–


Canterbury, TM2c, USNR, to help the wounded man. In the meantime Cutter gave the order to abandon ship and the men put the liferaft over the starboard, or offshore, side, and began taking to the water. Daley was dazed but obedient. He got in the water by himself, and Ensign Cutter and Ens. Robert W. Hyde, USNR, towed him to the raft.

The crew paddled and swam, trying to guide the raft away from the exploding boat and out to sea. They must have been working against the current, because after 2 hours they were only 700 yards away from the boat, and were considerably shaken by a tremendous explosion. After the explosion the flames subsided somewhat, but the hulk was still burning at dawn.

Several times the survivors saw searchlights’ sweep the bay from shore and heard the shore guns firing. They did not know the guns were firing at the 338, outside the bay. When the heavy battery had first opened on the boats, Davis ordered a high-speed retirement and the 338 laid a smokescreen. When the 337 did not come through the screen, Davis tried repeatedly to reenter the bay, but every time the 338 approached the entrance, the shore battery bracketed the PT so closely that it had to retire. Finally, knowing that the 338 would be a sitting duck not only for shore guns but enemy planes in daylight, Davis set course back to Saidor.

Daley died before dawn and was committed to the sea. That left three officers and eight men in the raft. Besides Cutter, Hyde, Watson, and Canterbury, there were Ens. Bruce S. Bales, USNR; Allen B. Gregory, QM2c, USNR; Harry E. Barnett, RM2c, USNR; Henry S. Timmons, Y2c; Edgar L. Schmidt, TM3c, USNR; Evo A. Fucili, MoMM3c, USNR; and James P. Mitchell, SC3c.

To say that the men were in the raft perhaps gives an exaggerated impression of comfort. It was an oval of balsa, 7 feet by 3, with a slatted bottom open to the waves. With 11 men, it was awash. Usually they did not even try to stay in it at the same time. Some stayed in it and paddled, others tried to guide it by swimming.

At dawn on the 7th the raft still was less than a mile off the entrance of Hansa Bay. During the morning the current carried it toward Manam Island, 6 miles offshore. Cutter wanted to go ashore on Manam, thinking it would be easier to escape detection in the woods than on the surface so close to Hansa Bay. Besides, the men could find food, water, and shelter ashore, and might be able to steal a canoe or a sailboat. All afternoon they paddled and swam, but whenever they came close to shore another current pushed them out again.

–225–


That night Cutter and Bales tried to paddle ashore on logs. If they could get ashore they would try to find a boat and come back for the others. After 3 hours the unaccountable currents swept the two exhausted officers and the raft together again. While they were away, Hyde and Gregory set out to swim to the island. They were not seen again.

During the night the men saw gunfire toward Hansa Bay, as though PT’s and shore batteries were firing at each other, but they saw no PT’s. By dawn of the 8th the raft had drifted around to the north side of Manam, no more than a mile from the beach. Mitchell already had set out to swim to the island. Cutter, Schmidt, and Canterbury were delirious that night. During the storm Canterbury suddenly swam away. Barnett, a strong swimmer, tried to save him, but could not find him. Soon after dawn, Bales, Fucili, and Schmidt also set out for shore. The others were too weak to move. Most of the men thought that Bales, Fucili, and Schmidt reached the island, but Watson, who said he saw Bales walking on the beach, is the only one who claimed to have seen any of them ashore. Soon afterward Japanese were seen on the beach.

Mitchell returned to the raft in the middle of the morning. He was only 75 yards from shore when he saw several Japanese working on the beach, apparently building boats. Plans to go to Manam were abandoned.

Soon after dark that night a small boat put out from shore, circled the raft and stood off at about 200 yards. There were two men in it who, some of the men said, were armed with machine-guns. They made no attempt to molest the men in the raft, but kept close to them until about 0400, when a sudden squall blew up, with 6- to 8-foot waves. When calm came again the boat was nowhere to be seen.

On the morning of the 9th the remaining men, Cutter, Barnett, Timmons, Watson, and Mitchell, saw an overturned Japanese collapsible boat floating a few yards away. It was only 15 feet long, but it looked luxurious in comparison with the raft. They righted it, bailed it and boarded it. Mitchell saw a crab clinging to the boat, and in catching it let the raft slip away. No one thought it was worth retrieving.

The crab was not the only food during the day. Later the men picked up a drifting cocoanut. The food helped some, but the men were tortured by thirst. They had lost their waterbreaker in the storm, and the cocoanut was dry. They were suffering, too, from exposure. Scorched by day and chilled at night, they were covered with salt water sores.

–226–


The night of the 9th and the morning of the 10th were monotonous agony. At noon, three Army B-25’s flew over, wheeled about and circled the boat. Cutter waved his arms, trying to identify himself by semaphore. One of the bombers came in low and dropped a box. It collapsed and sank on hitting the water. Then came two more boxes and a small package attached to a life preserver, all within 10 feet of the boat. The boxes contained food, water, cigarettes, and medicines. In the package was a chart showing their position and a message saying that a Catalina would come to pick them up.

The next morning a Catalina, covered by two P-47’s, circled the boat. The Catalina picked up the five men. Within 2½ hours they were back in Dreger Harbor.

A liferaft is a hard thing to spot. During the 5 days since the loss of the 337, planes by day and PT’s by night had searched for the survivors. Of those who tried to go ashore at Manam, little is known. A captured document indicates that 1 officer and 2 enlisted men were taken prisoner by the Japanese, but none of the crew of the 337 was reported as a prisoner of war.

Motortorpedbåt T 28 i full fart i skärgården 1943 Fo196168

All photos, Swedish Sjöhistoriska Museet maritime museum unless noted. This one is file no. Fo196168

Here we see HSwMS T 28, a T 21-class motortorpedbåt (motor torpedo boat) of the Svenska Marinen (Royal Swedish Navy) in 1943 as she planes on her stern, her bow completely above the waves. If she looks fast, that’s because she was– like 50 knots fast.

The Swedes in the 1930s had the misfortune of being sandwiched between a resurgent Germany and a newly ambitious Soviet Union, both having come up on the losing side of the Great War and suffered much during the generation immediately following. This fear went into overdrive as World War II began.

With a lot of valuable coast to protect, the Flottan’s plan to do so was the new Tre Kronor (Three Crowns)-class of three fast cruisers (kryssaren) who were to each serve as a flotilla flagship of a squadron of four destroyers and six motor torpedo boats while three  pansarskepps (literally “armored ships”) bathtub battleships would form a strategic reserve.

For the above-mentioned MTBs, Stockholm turned south, shopping with the Baglietto Varazze shipyard in Italy– which is still around as a luxury yacht maker). Baglietto’s “velocissimo” type torpedo boat, MAS 431, had premiered in 1932 and was lighting quick but still packed a punch.

MAS 431, via Baglietto

Just 52.5-feet long overall, MAS 431 was powered by a pair of Fiat gasoline engines, packing 1,500hp in a hull that weighed but 12-tons. The 41-knot vessel carried a pair of forward-oriented 18-inch torpedoes, a couple of light machine guns, six 110-pound depth charges for submarines (she had a hydrophone aboard) and was manned by a crew of seven.

MAS 431 craft proved the basis for the very successful MAS 500 series boats, with more than two dozen completed. These boats used larger Isotta-Fraschini engines which coughed up 2,000hp while they could putter along on a pair of smaller 70hp Alpha Romero cruising motors. The Swedes directly purchased four of these (MAS 506, 508, 511, and 524) which became T 1114 in 1939. These 55-foot MTBs could make 47 knots.

However, the Swedes weren’t in love with the wooden hulls of the Italian boats and went to design their own follow-up class of MTBs in 1941. The resulting T 15 class, built locally by Kockums with some support from Italy, went 22-tons in weight due to their welded steel hulls. However, by installing larger Isotta-Fraschini IF 183 series engines, they could still make 40+ knots.

Swedish Motortorpedbåt T 15. 5 Just four of these craft would be built by Kockums. The camo scheme and white “neutral” racing stripe were standard for Sweden’s wartime fleet. Fo101806

Nonetheless, there was still room for improvement. Upgrading to larger 21-inch torpedo tubes and stretching the hull to 65-feet, the T 21 class carried 3,450hp of supercharged 18-cylinder IF 184 engines which allowed a speed listed as high as 50 knots in Swedish journals. They certainly were a seagoing mash-up of Volvo and Ferrari.

Besides the torpedoes, the craft was given a 20mm AAA gun in a semi-enclosed mount behind the pilothouse while weight and space for two pintle-mounted 6.5mm machine guns on either side of the house and one forward was reserved. As many as six depth charges were also carried.

Torpedbåt, motortorpedbåt typ T 21

The T 21s proved more numerous than the past Swedish MTB attempts, with a total of 11 boats produced by 1943. They proved invaluable in what was termed the Neutralitetsvakten (neutrality patrol) during the rest of WWII.

Hkn Prince Bertil, Duke of Halland, who in the 1970s served as heir to his nephew King Carl XVI Gustaf, clocked in on Swedish torpedo boats during the first part of WWII before he was reassigned in 1943 as a naval attaché to London.

Due to their steel hulls, the craft proved much more durable than comparable plywood American PT-boats or the Italian MAS boats and, while the latter’s days were numbered immediately after WWII, the Swedish T 21s endured until 1959, still keeping the peace on the front yard of the Cold War.

In late 1940s service and throughout the 1950s they carried a more sedate grey scheme.

The T 21s were later augmented by the similar although up-gunned (40mm Bofors) T 38 class and finally replaced by the much-improved Spica-class, which remained in use through the 1980s with the same sort of tasking as the craft that preceded them.

The T-30, seen here in an idyllic peacetime setting, remained in Swedish service during the Cold War. The follow-on Motortorpedbåtar T38 class reached a speed of 51.6 knots during a speed test outside Karlskrona in April 1956.

At 139-feet oal, the Spicas were more than twice as long as the T 21s and carried a half-dozen torpedoes in addition to a 57mm Bofors gun.

However, that welded steel hull and the mild salinity of the Baltic has meant that at least one of the old T 21s, T 26 to be clear, has been preserved as a working museum ship in her Cold War colors and is still poking around, although she probably could not make her original designed speed at this point.

HMs derpy (but deadly) sharks

Thousands of Motor Launch (ML), Coastal Motor Boat (CMB), Motor Torpedo Boat (MTB), Motor Anti-submarine Boat (MASB), Motor Gunboat (MGB), Steam Gunboat (SGB), Fast Patrol Boat (FPB) and Fast Training Boat (FTB) craft served in the RN’s often forgotten Coastal Forces during WWII.

Scrapping with the Germans S- and E-boats up and down the English Channel and French coast, as well as birddogging U-boats and supporting both overt and covert landings in occupied Europe, these “splinter boats,” supported by legions of WRENs ashore, had a lot of pluck.

Though these, just two days before D-Day, look a little derpy.

Mosquito Boat flag and log from Normandy hits the auction block

A 48-star 34″x52″ flag, log and pictures from “Coral Queen/Coral Princess,” officially known as PT-520, a PTRon 35 80′ Elco that served in Europe during WWII is up for auction next week at Cowans.

The flag was used by PT-520 until August 25 1944 when the radio mast it was affixed to was shot away by a German shell and was preserved by a coxswain. According to Navsource, PT-50 was transferred to the Russkis in April 1945 and later scuttled in the Barents in 1956– but the flag and log remain.

From Cowans:

Serving in the European Theater of World War Two from June to November 1944, PT-520 participated in numerous actions against German sea and air forces in the English Channel and coast of France. This flag was present during its participation in Operation Overlord, where it was assigned to the “Mason Line”, a net of defensive measures on the western flank of the invasion preventing the attack of German ships. PT-520 was stationed two to three miles from Omaha and Utah areas, sweeping for mines and performing search and rescue operations. After the success of the invasion, PT-520 continued to operate along the French coast, rescuing downed pilots, fending off aerial raids and engaging German minesweepers and fast attack craft. The log states that during its operational career, the vessel sunk two R-Boats, two E-Boats, and one “T.L.C.”
