1943 Luftwaffe operation in World War II
The action off Cape Bougaroun (Cap Bougaroûn) [Attack on Convoy KMF 25A], was a "Luftwaffe" operation against an Allied naval convoy off the coast of Algeria during World War II. The convoy of American, British, Greek and Dutch ships was attacked on 6 November 1943 by 25 German bombers and torpedo-bombers.
Six Allied vessels were sunk or damaged and seven German aircraft were shot down. The Germans had achieved a tactical victory, though the Allied fighter escorts and warships were praised for shooting down so many bombers. At least 1,400 men and women were killed but the rescue effort led to the saving of over 6,000 passengers and crew.
Background.
Task Group 60.2.
Before the routine convoying of transatlantic convoys to Bizerta (now Bizerte) in Tunisia, US convoy escorts occasionally supplemented British convoy escorts in the Mediterranean. Task Group 60.2 (Captain Charles C. Hartman USN) escorted Convoy UGF 10 across the Atlantic to Oran and then escorted several convoys in the Mediterranean. On 3 September 1943, the convoy being escorted was attacked by the "Luftwaffe", which failed to hit merchant ships but torpedoed the destroyer in the stern, the destroyer making its own way to port. The task group escorted two more convoys and was then assigned to escort Convoy KMF 25A, a troop convoy from Britain.
Hs 293 glide bombs.
Kampfgeschwader 26 began operations over the Mediterranean as a torpedo-bomber unit in early 1941. II./KG 26 was equipped with He 111 torpedo-bombers and III./KG 26 flew Junkers Ju 88 torpedo-bombers and practiced (pincer-attacks) when a "Staffel" of torpedo-bombers swarmed targets, to prevent them from maneuvering as they could to evade torpedoes dropped from one direction. A specialist "Luftwaffe" unit, "Kampfgeschwader 100" (KG 100) had been transferred from Italy to a base near Marseilles in July 1943, having received more than fifty Dornier Do 217 (special combat aircraft).
II./KG 100 received Dornier Do 217 E 5 aircraft, equipped for the Hs 293 a wireless guided glide-bomb, accelerated by a rocket motor and Dornier Do 217 K 2 bombers, adapted to use the Fritz X guided bomb, equipped III./KG 100. Both went into action in July 1943 against shipping in the Bay of Biscay and the Mediterranean. On 25 August 1943 twelve Do 217E‑5s of II./KG 100, escorted by seven Ju 88C‑6s, attacked the sloops and and the frigate . One man killed and 16 injured on "Bideford". Two days later, "Egret" was hit by an Hs 293 from II./KG 100 west of Vigo and sunk with 198 men killed; the Canadian destroyer was severely damaged.
Convoy KMF 25A and escorts.
Convoy KMF 25A consisted of 26 merchant ships and troop transports escorted by 15 warships, from Liverpool to Alexandria via Palermo and Naples. Task Group 60.2 (TG 60.2) comprised the British light cruiser , the destroyers , , , , , , , the destroyer escorts and and the s , , and the Greek HS "Kanaris" and HS "Themistoklis". On 27 October 1943, Convoy KMF 25A sailed from Britain.
Prelude.
Voyage.
After passing Gibraltar, the ships were escorted by the Royal Air Force (RAF) in relays. The convoy sailed in columns of seven to nine ships each from Mers-El-Kebir to Naples but formed three columns to pass through the Tunisian War Channel (the Sicilian Narrows). "Laub" sailed ahead of the fleet on radar watch. "Mervine" led the warships in a circular course around the three columns. "Beatty" and "Tillman" were astern and "Mervine" was ahead, under an overcast sky with the cloud base at . On 6 November, "Haydon" detected an aircraft to the north soon after noon but this was transmitting Allied Identification friend or foe (IFF).
On 26 November, Ju 88s on reconnaissance reported a convoy of 15–25 vessels, including a troopship, off the North African coast. The convoy was protected by a Beaufighter, a Wellington and several single-engined fighters. Convoy KMF 26 was an eastbound troop convoy of 22 merchant vessels and 15 escorts from the Clyde carrying mainly United States Army Air Forces (USAAF) personnel to Alexandria, via Gibraltar. Twenty-two He 177s of II./ ( Major Rudolf Mons), took off from Bordeaux-Mérignac, each carrying two Hs 293 glide-bombs. One He 177 crashed on take-off due to an engine failure and caught fire, four of the crew being killed. The rest of the He 177s were followed by 18 Heinkel He 111s from II./KG 26 and 15 Junkers Ju 88s from III./KG 26. Night was falling when the bombers sighted the convoy off Béjaïa, in Algeria.
Action.
The convoy went to action stations at 17:36 and about 17:45, the convoy was north of Philippeville off Cap Bougaroûn in Algeria (37°05′16″N, 6°28′03″E) when "Laub" detected six aircraft to the north but these were also transmitting Allied IFF. Hartman signaled the destroyers to make smoke and prepare for action. The passengers were also ordered to go below deck and remain there until the threat was over. At 18:00 "Tillman", on the port side of the convoy, detected a contact to the north-west at , sighted aircraft soon afterwards and opened fire.
As the He 177s attacked, Spitfire VBs from the Free French 1/7, P-39 Airacobras of the 350th Fighter Group (USAAF) and Beaufighter VIFs from 153 Squadron RAF and the 414th Night Fighter Squadron (USAAF) arrived. As the German bombers came within range, the escorts and the merchant ships opened fire. Seconds later, the Germans began glide bombing, the Hs 293 booster rockets looking orangey-red. The bombers concentrated on "Tillman" which escaped damage by rapid maneuveres and accurate anti-aircraft fire. A He 177 dropped a glide-bomb about off the beam and the automatic weapons on the port side fired at the bomb. When the projectile was away the bomb was hit and it fell into a steep dive, crashing off the port side.
A second bomber dropped a glide-bomb to port as "Tillman" was steered back to its place in the convoy screen. "Tillman" turned towards the bomb and the automatic weapons fired at the bomb as the main guns engaged the bomber. The bomb passed over the bows, turned around and hit the water about to starboard as the bomber was hit by the 5-inch guns and exploded. A glide-bomb from a third He 177 hit the sea to starboard. Concussion from the bomb-explosions damaged the fire-control radar and when torpedo-bombers flew low to the port of the convoy, the gunners resorted to aiming by sight. Torpedoes were dropped by a wave of the torpedo-bombers, "Tillman" combed the tracks and at 18:18 two torpedoes were seen to pass down the starboard side, one exploding in the wake, concussion damaging the hull at the stern.
"Beatty" (Commander William Outerson) on the starboard side of the convoy detected two aircraft showing Allied IFF at 18:05 astern but one was seen to be a Ju 88 and Outerson inferred that the IFF was being transmitted by German aircraft. The smoke screen obscured some of the view, two Ju 88s appeared out of it, were engaged by the anti-aircraft armament and turned away. Thirty seconds after the Ju 88s had sheered off, a torpedo hit the after engine room, which broke the ship's back, caused a power-cut throughout the ship and flooded the engine-room. One officer and six men were wounded and "Beatty" slowly began to sink at 27°12'N, 06°16'E, west-north-west of Philippeville.
All hands were called on deck but when the ship did not settle, they assisted damage-control parties and began throwing overboard anything that moved. "Beatty" began slowly to settle at about 21:00, "Laub" took off some of the crew and began to rig a towline but it became clear that "Beatty" could not be saved. At 22:30 as the list reached 45° the remaining crew members abandoned ship, it broke into two parts and sank. About three torpedo-bombers got through the fighters and the escort screen and hit  GRT (William C. Renaut), at 37°12'N, 06°16E, that sank some hours later at . "Santa Elena", carrying 1,965 Canadian troops and nurses was also hit; four crewmen were killed and the American armed guard on board freed several men who were trapped below, 2,163 people surviving. The Dutch troopship "MS Marnix van Sint Aldegonde", with 2,924 troops on board, was severely damaged but had no fatalities.
Aftermath.
Hartman ordered the commander of Destroyer Squadron 16, Captain C. J. Cater, to oversee the rescue operation with five of the destroyers as "Monterey" and "Ruyz" took off passengers from the damaged troopships, in a heavy swell. Destroyer Division 32 (Commander J. C. Sowell) comrpising , , and sailed from Algiers but were too late to assist the damaged ships. Tugs from Philippeville were sent to assist and took the damaged liners in tow to Philippeville. "Santa Elena" sank just short in the outer harbor and "Marnixx" grounded as attempts were being made to beach it.
Rear Admiral Carleton F. Bryant endorsed Hartman's after action report but was critical of the British organisation of the convoy, writing that the convoy commodore and the escort commander should have been from the same service. Bryant criticised the slow speed of the convoy and should have been at the speed of the slowest ship, not the that it was moving. Once in the Mediterranean, the convoy should have been divided into a fast group and a slow group to benefit from the -speed of some of the ships; "Monterey" capable of should not have been limited to and the air cover should not have been withdrawn at dusk.
Casualties.
About 300 people were killed by the bombing of "Rohna"; most of the lifeboats were destroyed or damaged and many of the life-rafts were found to be unusable. "Rohna" sank within an hour; in the growing darkness and swelling sea the rescuers had great difficulty, leading to the deaths of 1,015 American servicemen, 120 British and Indian crew members, eleven gunners and three Red Cross workers were killed. Four crew were killed in "Santa Elena" and the American armed guard on board freed several men who were trapped below, 2,163 people surviving. "MS Marnix van Sint Aldegonde", with 2,924 troops on board, was severely damaged but with no fatalities. The rescue operation saved 6,228 people, including the crew of "Beatty". The US Navy Armed Guard gunners on board the US ships claimed five aircraft shot down and one probable. Later examination of German records by Gross (2006) showed that three He 111 torpedo-bombers of I./KG 26 and four Ju 88 torpedo-bombers from III./KG 26 were shot down, including Eberhard Peukert, the commander () of 8.. Two He 177s of 4./KG 40 and two of 6./KG 40, a He 177 of 6. ditched off Montpellier and one He 177 was written off after crashing on landing.
