NEW GUINEA: Australian and US troops of the 3rd Australian Division (GOC Maj-Gen Savige) attack Observation Hill overlooking Japanese positions at Mubo, lying on the southern approaches to Salamaua. It possesses an airstrip, which is vital in Papua New Guinea and also sits astride the only track for miles linking the coastal landing site of Nassau Bay with the inland Bulolu Valley.

The Japanese were in strength at Mubo. Deceptive patrols and small attacks prior to the battle by 15 Australian Brigade (militia and commandos) caused Col Araki to denude Mubo of troops, leaving it to be defended only by II/66 Bn.

17th Brigade AIF (2/5 Bn AIF, 2/6 Bn AIF and I/162 US Inf Bn, supported by 1st Aust Mtn Bty and 218 US Fd Arty Bn) launches a double-envelopment against Mubo. Over the next five days the US and Australians conduct numerous small attacks and fighting patrols in close contact with the enemy. (Michael Mitchell)

CARIBBEAN SEA: MS Poelau Roebiah in Convoy TAG-70 was torpedoed and sunk by U-759. Most of the 68 crewmembers, 24 armed guards and 31 US passengers on board abandoned ship in four lifeboats. Two crewmembers were lost. The survivors in three boats were picked up by a USCG cutter and several escort vessels. USS PC-1253 found the whaleboat of the master and brought the occupants to Guantanamo.

ATLANTIC OCEAN: The German submarine U-951 is sunk about 308 nm (570 km) west of Lisbon, Portugal by the crew of a B-24 Liberator of the USAAF's 1st Antisubmarine Squadron (Heavy) based at Port Lyautey, French Morocco. All 46 crewmen in the U-boat are lost.

At 0607 German submarine U-185 carries out two attacks on convoy BT 18 (Bahia, Brazil, to Trinidad) torpedoing an 8,000-ton U.S. freighter and an 8,000 ton tanker about 153 nm (284 km) east of Fortaleza, Brazil, in the first assault. The freighter, the JAMES ROBERTSON in station #21 is struck by two torpedoes in the #2 and #3 holds. The explosions destroy the engine room bulkhead and blow several hatch covers off, littering the deck with bits of metal, rock ballast and pieces of lifeboats. The holds flood to the tweendecks and he ship buckled at the #3 hatch. She then careens through the columns of the convoy with running engines and the rudder jammed at hard right, making a complete circle. She collides in succession with the American steam merchant ALCOA BANNER in station #32  and moments later with the Brazilian steam merchant GOIAZLOIDE in station #33 at the #1 hatch. A part of the eight officers, 36 crewmen and 25 armed guards (the ship was steaming with one 4in and nine 20mm guns) was ordered to abandon ship in two lifeboats and rafts. One boat swamped during launching and others jumped overboard and swam to the rafts, one of the armed guards drowned. The 21 men on the rafts, the men in one of the boats and five men in the water are picked up by the submarine chaser USS PC-575 and landed in Trinidad on 15 July. The master and 20 men abandoned ship after the collisions in two lifeboats and stood by until morning when they reboarded the vessel to recover personal effects, but the ship later went down by the bow. 24 men, including three survivors from the William Boyce Thompson were picked up by the Brazilian escort vessel CS-55 and landed at Fortaleza on 9 July. The 14 men in one of the remaining two lifeboats landed at Fortaleza on 9 July and the other boat landed at Cascavel, Brazil the same day.

At 0829, U-185 attacked the convoy for the second time and reported hits on a tanker and an ammunition ship that were sinking slowly. The ships hit were SB Hunt and Thomas Sinnickson. The SB Hunt in station #51 was hit by one torpedo on the port side at the bulkhead between the pump room and #4 tank. The explosion opened a hole 45 feet by 35 feet in the side but the tanker was able to continue with the convoy. None of the eight officers, 29 crewmen and eleven armed guards (the ship was armed with one 5in and two .50cal guns) reported injuries. The SB Hunt arrived at Trinidad for temporary repairs and after permanent repairs carried out in Galveston she returned to service on 4 November. (Jack McKillop and Dave Shirlaw)
