Merry Christmas to you all! :D
As a present from ABS Productions we have a tale of heroism on the high seas.
Operation Blue Typhoon
In November 1935 the Argentine secret agent Jackal in the Iberian embassy in Pretoria received information that a routine convoy of 22 merchant ships was due to depart Durban on the 13th headed for Buenos Aires. It would have the usual escort and destroyer screen but no cruiser support. His report was relayed via courier to another agent, Cicero, in the Iberian Embassy in Argentina who got the information to Argentine Naval Intelligence via a courier [Note 1].
Under pressure from the government to do something about the incoming African supplies as it seemed likely that the Brazilian Front would collapse at any moment the Chief of Staff Almirante Peablo quickly organised Operation Blue Typhoon. Even a partial success might slow or temporarily halt enemy convoy sailings and buy much needed time for the Argentine Army to rebuild some strength before the next enemy offensive.
On the 18th the cruiser General Belgrano would set sail from Comodoro Rivadavia and head out into the Atlantic and intercept the convoy. Given the light escort the Navy felt sure of success and a much needed victory. The cruiser would sail alone; no escorts would hamper her speed. It was to be a hit and run raid. Total radio silence was to be observed although the codeword “Typhoon” would be sent when the convoy was engaged.
Capitan de Navio Nico Marlboro received his orders on the 17th, ordered his crew aboard from shore leave that night, provisioned and fuelled and casted off at 04:30 from Comodoro Rivadavia. As the pilot guided the cruiser out of the harbour and into the channel the crew packed away the stores and stopped grousing about their cut-short leave as the prospects of action enlivened the crew [Note 2].
Luitenant Lilibung, captain of the J-1, J Class submarine, was on patrol six miles offshore from Comodoro Rivadavia. He lowered the periscope, “that’s the second minesweeper, something is leaving harbour, a big ship.” He was suffering from bad luck this trip, his radio was not working properly and he was finding it difficult to maintain trim. As he manoeuvred to get around the minesweeper he raised the periscope and again peered into the night. Nothing, he could see nothing and yet his seaman’s sixth sense told him a big ship was out there. “Steer red 30, keep her steady, watch the trim.” The hydrophone operator picked up high speed propellers, maybe a cruiser and then identified a destroyer 3,000 meters off the port bow. “Dive to 100! Green 60 degrees, maintain collision stations!” The dreaded ASDIC ping did not come and the destroyer passed along the port side and far away astern. Lilibung breathed a sigh of relief, they were safe but the cruiser was too far away to catch submerged and it was too dangerous to surface this close to the coast. He sighed; tomorrow he would send a report to Naval HQ Mar del Plata.
The General Belgrano emerged into the Atlantic; the weather was clear and the seas smooth. Capitan de Navio Nico Marlboro let his men unwind. Those off duty sunbathed on the quarterdeck or on the turret roofs, others read, some did a spot of fishing with simple tackles while the AA gun crews swept the skies and the gun directors swept the horizon. Everything seemed to be going well; conditions were perfect and under radio silence Marlboro felt sure that the African’s were unaware of his presence. After two days heading east the Belgrano turned northeast to bring her towards the convoy routes. naval intelligence had estimated which route the convoy would use (the normal Durban-Buenos Aires route) and Marlboro aimed for this. As far as he knew only one other convoy, a homeward bound convoy of ten ships, was at sea.
Unknown to Marlboro or Naval Intelligence a cruiser of the RSAN 10th Cruiser Squadron, the Douala II, on routine patrol on the northern convoy routes, was ordered to refuel from a tanker with the convoy on the 19th and arrived in the area on the 20th. On the 19th the 6th Destroyer Flotilla, 1st Division, comprising of RSAN Halberd, RSAN Javelin and RSAN Glaive departed for home having escorted the convoy into the mid-Atlantic without mishap. RSAN Javelin remained to serve as a flagship for the remaining escorting force made up of the 3rd Escort Flotilla, 2nd Division with the frigates RSAN Rio Olimer Grande, RSAN Rio Cebolatti, RSAN Rio Tacuari and RSAN Rio Daymàn.
At 09:24 on the 20th a look-out aboard the General Belgrano spotted smoke on the horizon. Capitan de Navio Nico Marlboro immediately leapt up from his seat in the open bridge and ordered all crews to combat stations. The Gunnery Officer Teniente de Navio Salvador in the main director atop the foremast confirmed, “several smoke plumes, two large merchant ships visible on horizon. Certainly a convoy captain.” Marlboro moved into the conning tower and ordered a top speed interception course. The sun was up in the east, Marlboro decided to come up from a southerly direction and attack the convoy from astern. At 08:44 a Wapiti V had been launched from the catapult and now radioed its first sighting report, “Convoy sixteen miles northeast, 3 escort ships and sixteen merchant ships, two tankers. Are heading 230 degrees but altering course northward. Conditions good with some haze, clouds forming to the north.” As the Belgrano altered course it was obvious that the convoy had either spotted them or the aircraft and was altering course while the escorts altered stations to form a defensive line. Even so the Belgrano at full speed soon closed the gap and had the convoy within effective range of her 150mm guns.
The Gunnery Officer Teniente de Navio Salvador began feeding range data to the forward turrets as the Wapiti made report before breaking off to avoid AA fire. The Belgrano broke radio silence to broadcast the codeword “Typhoon.” At 09:37 Belgrano turned to open the arcs for A, B and C turrets and at 09:40 the all three turrets opened fire on a large 5,000 ton steamer [Note 3]. By this time the RSAN destroyers (in fact RSAN Javelin and the escort Rio Olimer Grande) were approaching head-on to minimise their target aspect at full speed to close the range to launch a torpedo attack. Already two escorts were laying a smoke screen and the convoy began to scatter to the north. The third half-salvo scored a hit on the steamer as Marlboro turned to port to bring his after guns into action while his forward guns dealt with the destroyer threat. The secondary 100mm guns began firing as the destroyers turned to launch torpedoes; RSAN Rio Olimer Grande is hit astern by a 150mm shell which causes a secondary explosion shortly afterwards [Note 4] her bows shot upwards as the stern quickly sank. Although RSAN Javelin fired several rounds none of the enemy shells hit but a few splinters did come aboard. The enemy destroyer retired under smoke to regroup as the after 150mm guns under local control from the after rangefinder began shelling a large tanker that loomed out of the smokescreen [Note 5].
The starboard lookout spotted torpedo tracks to starboard but Marlboro calmly issues orders to comb the tracks, once the danger is over he resumes his course to open the arcs of his after turrets.
At 10:09 Gunnery Officer Teniente de Navio Salvador scores another hit, this time a 100mm hit on RSAN Rio Tacuari’s bows as she turns to make an attack with her 105mm guns while still laying a smoke screen. Only one enemy destroyer succeeds in launching a spread of torpedoes. Once again Marlboro alters course to improve his arcs. As the cruiser turns however a 105mm shell hits the forecastle wrecking the windlass and another ricochets off the main belt harmlessly. As Marlboro starts a new parallel course Teniente de Navio Salvador begins aiming all the 150mm guns onto the convoy and splits targets. The RSAN Rio Tacuari still laying smoke is assigned to A and C turrets while X and Y turrets aim for another cargo ship much further north which is soon obscured by smoke. The RSAN Rio Tacuari comes under heavy fire at 10:13 and at least two 150mm hits are recorded amidships. She slows down and begins to founder as two 100mm shells from Belgrano’s secondary armament find their mark. In the conning tower Capitan de Navio Nico Marlboro nods, it seems to him that the convoy is in his hands, there is little to stop him sinking the ships before they scatter too far. He noted the escorts seemed to have broken away further north and seemed disinclined to engage again as they shepherded the slowest merchants to safety.
At this point the cruiser RSAN Douala II dashes through the smoke screen, her forward guns spurt fire at a range of 9500 meters. She had been on the other side of the convoy waiting to link up with the tanker when the Belgrano appeared. Gunnery Officer Teniente de Navio Salvador soon spots this new threat and assigns the forward turrets to engage her. Marlboro was shocked but using his binoculars he noticed the Douala II was laying high in the water assumed she had empty bunkers. Marlboro gave his commands calmly, “steer 240 degrees, let’s open the range and concentrate on the cruiser. Secondaries are to keep firing on the enemy escorts on the starboard side, keep me informed if they close. Tell the Chief I want all the power he has, we can’t let the enemy cross the T.” [To be continued...]
[Note 1] Cicero was a typing clerk, Juan de Horengo who had been making tip offs to the Argentine Navy since 1926. The Ministry of Security doubted his integrity and he proved to be talkative. In December 1935 he died in a "car crash" during an air raid.
[Note 2] Capitan de Navio N. Marlboro; age 35; born 1901, entered the Navy at 16 and worked through the ranks he took his first command in 1925 of the cruiser Commodoro Py and in 1927 took command of the sailing ship Presidente Sarimento. He was the first commanding officer of the General Belgrano and spent six months in Germany when the ship completed. He was in command of the cruiser throughout the war.
[Note 3] The SS Guadalupe, she was hit by one 150mm shell in the forward hold causing some flooding but made Grand Uruguay safely.
[Note 4] The RSAN Rio Olimer Grande suffered a direct hit in her after 105mm magazine, this exploded wrecking her stern and she quickly sinks. 70 of her crew perish.
[Note 5] The 5,800 ton SS Saturn Derrick, only two years old and one of SAE’s newest tankers. She was hit just abaft of the forward superstructure wrecking a pumping room and causing an oil leak. Some of this caught alight and she burned for four hours but her gallant crew managed to extinguish the blaze and save the ship.
