April 1
[A] Units of the Gunboat Support Squadron, Rio Parana Support Squadron and the 2nd River Fire Support Squadron have come under heavy aerial and land bombardment as they attempt to reach Encarnation with two Tabors of Infantería de Marina. [Note] The beached gunboat Patria, now a static gun battery to protect the town of Formosa was dive bombed and three near-misses were recorded.
[Note] At this point the RSAA still believed the ships were going to evacuate the trapped force and not until the 2nd was it clear reinforcements had been landed.
April 2
[A] Just after dawn the elderly gunboat Capitan Cabral was sunk by R17 and R18 of the RSAN but La Plata succeeded in sinking two small river transports. As the force neared Encarnation the RSAF attacked with some forty assorted twin and single-engined bombers with around twenty fighters as escorts. The Los Andes was hit by three 500kg bombs; one penetrating the main 75mm ammunition magazine, the ship blew apart taking all but twelve of its crew.
However the RSAF was soon faced with a counter-attack. The newly-formed General San Martin Squadron manned by foreign pilots was thrown into the fray with some nineteen fighters from the Aerea Regimenta Paraguay. The RSAF pilots noticed a new fighter in the skies above Paraguay, silver and white monoplanes with patriotic and revolutionary slogans painted in red along the fuselage sides, the RSAF pilots claimed them either to be the supposed new I-101 fighter or Italian CR.35 fighters [Note]. The twelve pilots of these sleek machines managed to down six bombers between them and strafe a gun battery into the bargain. Total FAA claims were twenty-six kills and nine probables for the loss of only seven fighters. The RSAF claimed ten kills for the loss of five F-6B fighters and nine bombers. The gunboats arrived unmolested and they disembarked their troops and began a six-hour barrage of known RSAA positions. This fire helped the Marines to retake some ground lost earlier including Hill 46 which gave a commanding view over the eastern part of the town. The 2nd River Fire Support Squadron will stay in the area to give fire support and attack RSAA craft.
[Note] These were in fact Italian CR.35 fighters manned by pupils and graduates of the Bergamini Tactical School.
April 4
Planes of Air Fleet 5 covering the northern flank of Grand Uruguay have attacked Brazilian positions and army depots. Intelligence reported preparations for a large assault and so 14th and 21st Bomber Wings flew several sorties with their aging Villant B-8CN bombers. Because of the old planes limited defensive capabilities they were escorted by F-3C Warhawk fighters. About 20 tons of bombs have been dropped against enemy targets and 10 Brazilian planes shot down during air battles. In return the RSAF reports 7 Pigs lost over enemy territory and another 6 due to landing crashes. Of their fighter escort only three Warhawks failed to return to their bases but sadly all three pilots seem to have died.
April 5
[A] The Units of the Gunboat Support Squadron and the Rio Parana Support Squadron on their way back to Formosa last night clashed with light forces of the RSAN. Both Humaita and Paraguay reported an R-Boat sunk [Note] and three small Army craft apiece while La Plata was damaged by light cannon fire she sank a small river steamer. During the day the force successfully engaged and knocked out a battery of artillery whilst under fighter cover including the General San Martin Squadron which used its A-1 Mapache ground-attack fighters to attack several RSAA dumps.
[Note] R13 and R15 were escorting an army supply convoy when they were surprised by the unreported presence of the Argentinean flotilla. In a fierce battle both units were hit and had to retreat under smoke before getting overwhelmed. On their way back to their basis R15 lost power and had to be taken in tow by her sister. However, progressive flooding forced the crew to abandon her before she finally sunk. Casualties were 9 dead and 12 injured on the RSAN vessels. R13 is rated at 76% after the fight and inactive until repairs.
April 6
[A] The Compania Argentina de Marinanavegacion Rividavia today confirmed all work will cease on the two civilian mail ship carriers and the super-liner La Argentina currently under construction in Atlantis for the foreseeable future. Shares fell shortly after the announcement.
[S] At Encarnation RSAA troops under pressure have begun withdrawing to more solid defensive lines, a ruthless charge by the 7th Zulu Regiment brought them time but sixty soldiers were killed in the charge. UPAF forces in the area are regrouping and forming bands behind the African lines to cut communications and sow confusion among the defences.
April 8
[A] The gunboats Humaita and Paraguay have sailed up the Rio Parana to land two batteries of 75mm guns and much need food and ammunition. They have so far faced less opposition and Argentine commanders believe the Africans are withdrawing across the river.
April 8
[S] Off Montevideo a submarine attacked incoming elements of the 4th Battle Squadron. A spread of three torpedos could barely be evaded by RSAN Hyperion and eye withnesses of her crew reported one fish to pass in just about 2 meters distance. Escorting destroyers Galateia and Hipponoe immediately attacked the subs position. They dropped 32 deapth charges over half an hour and circled for another 30 minutes should the submarine surface. [Note] Without any further trace of the enemy the two ships finally followed 4th Battle Squadron into the harbor.
[Note] Only one submarine failed to return back to her base during those days, Brazilian Golfinho, which just successfully attacked a South African freighter 8 hours earlier. A post-war check of known submarine operations and log files revealed she must have been responsible for the attack as no other subs log reported an attack against a South African capital ship on that day. The cause of her loss remains unclear as her wreck was never found but it is most likely she was sunk by the destroyers counter-attack.
April 9
[A] A six hour barrage by heavy 155mm batteries around Resistencia has devastated part of the town of Corrientes on the Grand Uruguayan side of the Rio Parana and forced many of it inhabitants to flee. RSAA gunfire replied most of the afternoon but two FAA bombing raids this evening seemed to find their targets in the town, smoke and pillars of fire could be clearly seen from Resistencia.
April 10
[S] The "Pony Express" have raided Viedma yet again and attacked a lone freighter in the area but failed to sink it.
[A] UPAF and Argentine forces have begun a major offensive against the Paraguayan capital city Asuncion supported by aircraft and tanks. The four remaining Loyalist Air Force aircraft were destroyed on the ground and by dusk the airfield was in UPAF hands.
April 11
[A] Today there have been a series of aerial fights along the entire border. Four bombing missions by Audax, Mapache and M.B.2 bombers have hit three important RSAA supply dumps and the main railway sidings at the city of Parana on the shores of the Rio Parana. Fighter missions flown were mainly patrols along the border and one F-3C Warhawk has been claimed as damaged. Tonight some six M.B.1 twin-engined bombers have left to bomb strategic targets deep inside Grand Uruguay.
[S] In Montevideo DD Amphitrite, damaged in a gun fight on Mar 17, enters the yards for repairs which will take two month and cost a total of 142ts.
[A] In Asuncion fighting has reached the inner parts of the city. Some 2000 Loyalist troops have surrendered or switched sides in the last 24 hours, Colonel Ernesto, the city garrison commander, also switched allegiance to the Rebel cause and turned the guns of his 300 soldiers in the eastern part of the city on their former allies.
April 12
[A] Colonel Ernesto and the Argentine commander of II Division have accepted the surrender of the city of Asuncion by the remaining loyal Government forces. Some 3400 soldiers are now being disarmed and II Division has already begun moving southwards leaving two Regiments to guard the city and maintain law and order. Elements of the Area Regimenta Paraguay have moved into the former airport and are now resuming attacks on Loyalist supply lines deeper in the eastern half of the country.
April 13
[S] From an air field a few miles outside Asuncion the RSAF rescued Paraguays political leader. In a brave action an AeroDynamics Type 13 Skyliner landed at dawn only to start again 10 minutes later, now with President General Hector Ramon Garioza Ruiz Diaz and his staff aboard. Under cover of twenty F-6B fighters the Type 13 could bring her important freight to an unknown place in Grand Uruguay. Rumours say Garcia, albeit not a political ally to the SAE government, will be given a basis in Grand Uruguay allowing him to keep up faith in his powers among remaining loyal Paraguayan troops which will help bind Argentinean and UPAF forces and release pressure on the RSAA.
April 14
[A] Today the Ministry of Foreign Affairs has issued a statement concerning the confirmed transit of the evil Paraguayan dictator General Hector Ramon Garioza Ruiz Diaz to Grand Uruguay with the assistance of the RSAF. "It has become clear to the world today that the imperialist South African Empire has been propping up General Diaz's cruel and vicious regime in Paraguay and now have offered him refugee in their territory as he begins to lose the war and his position. Now the freedom fighters of the United Paraguayan Anti-Government Front have secured a vital victory it seems assured that the RSAA must soon be forced to leave Paraguay as the remnants of the shattered Loyalist Paraguayan Army collapses. The SAE will not deny the world of seeing General Diaz standing trial for crimes against humanity and they will not be able to protect forever. Only now we can guess with this implicit show of support that the African aid system was not totally honest and that many of the supposed Argentine arms shipments to rebel groups were, in fact, RSAA shipments to the illegal Paraguayan Government."
[S] In a response to Argentine claims the Foreign Minister in Pretoria made this speech. "In response to Argentina's latest outburst it must be remembered that Argentina openly taking the side of the UPAF revealed their agitation in the past months and years for geopolitical expansion and their cooperation with the madmen in Brazil fanned the spark of conflict in the region. Argentina, and Brazil, are responsible for this war that has begun on the shoulders of the innocent population of Paraguay. Argentina feels free to blame others of crimes against humanity but has, and is, committing them themselves while we speak by waging and encouraging this bloody civil war. This has forced us to openly support our neighbour Paraguay, under the rule of a legitimate government, against Argentinean agitation. Argentine propaganda peddlers pushing new lies about their own people's work trying to blame innocent people! PHP is and always has been a free organization, formed by both Argentinean (!) and SAE privateers, and their only intention is to help people. People that suffer from Argentinean agitation in Paraguay first place! This is why we still stand firmly behind the legitimate government of Paraguay and remain committed to the people of Paraguay."
April 15
[A] Two A-18 bombers attacked a series of trains leaving Cordoba station this morning killing seventeen passengers and destroying some fright cars. Also two I-100A fighters attacked two Martin-Zand RB-5B reconnaissance planes just south of the city. One was shot down by AA fire near the main airbase and the other escaped. Three bombing sorties were flown today and the last sortie resulted in a dogfight over Buenos Aires. One I-99 fighter was lost with a further two damaged (one made it back to friendly soil) and in return one F-6B was shot down by Lieutenant de Aero Roja in his I-100A.
April 17
[S] Devestator bombers have flown one of the wars heaviest attacks. The 2nd Strategical Bomber Wing send 34 of the large airplanes against industrial installations near Asuncion to prevent the UPAF and Argentinean forces in the area to make use of these plants. Over 60 tons of explosives have been dropped in a devastating blow entirely destroying the target factory. Only one JFM B-14A was lost to AA fire while another was badly damaged and written off after landing. Escorting Swollow fighters faced little opposition but claim two victories over enemy planes against one of their own.
[A] The cruiser General San Martin with two Mendoza Class destroyers has returned to Viedma after yet another successful mine laying operation off the River Plate estuary.
[S] From Libreville the 3rd R-Boat Flotilla including tender RSAN Walker Bay will deploy to South America. The ongoing conflict has causes early losses among the fleets light crafts which need to be compensated.
April 18
[A] III Corps in a pre-emptive strike has begun a full scale offensive along the Atlantic coast with the objective of capturing the important port of Mar del Plata. The Corps V and VI Divisions are being supported by the Infantería de Marina Brigada "Bahia Blanca". General Manuela is in overall command of the operation. Last night a five hour barrage lifted and troops moved forward with tank support against SAE border posts just after dawn. Fuerza Aerea Argentina fighters and bombers made numerous sorties to bomb all RSAF airfield and forward RSAA dumps and positions in the area. Ten of our aircraft are missing.
B Company of 502 Regiment (2nd Regiment of V Division) was largely wiped out trying to capture an RSAA strongpoint on the border protecting a little village. The brave men charged the wooden pillbox but with little success and the RSAA. B company suffered 99 casualties and 27 killed.
Further to the south a platoon of A Company supported by a battery of 75mm field guns and a three T-1M31 tanks attacked another RSAA strongpoint with trenches and pillbox protecting a the main coastal road. After a hard battle the strongpoint was thoroughly destroyed by artillery fire but the truck-mounted infantry failed to cross the border and were driven back with heavy casualties (38 plus 11 killed) and two of our tanks were knocked out as they tried to cross the enemy trenches.
[S] In Cape Town a new coastal defense ship is laid down. The ship, so far last in a design process that started with RSAN Nagelring in 1924, will an evolutionary step forward from the earlier Gungnir-design and fill in the last slot for CDS as allowed under the terms of the Cleito Treaty. The most remarkable design feature are the ships 25cm guns - a caliber already used for CDS earlier but then abondoned for a newly designed 21cm gun in 1929. The expected increase in ROF could not be achieved with the lighter gun so the heavier shell is favored again.
April 19
[A] The Commander-in-Chief's yacht/ sloop Capitan de Navio Parker has been commissioned today in Bahia Blanca. After a short trial run she provisioned and headed south to safer waters for her working-up.
[A] The "Pony Express" at around 19:25 tonight made a short five minute bombardment of Bahia Blanca. Shore defences put up a stout defence and three torpedo boats were sent out to attack the enemy but by the time they cleared the harbour the four Arion Class ships had fled eastward. At least one 4in hit was obtained [Note].
[Note] The shell hit RSAN Sleipnir amidships at starboard. Fragments damaged her catapult which no longer can be used making flight operations impossible. The ship is now rated at 98%.
April 20
[A] C Company of 501 Regiment succeeded in getting over the border and at dawn attacked the small settler town of New Blomfontein along the main road to Mar del Plata. Three T-1M31 tanks provided support as well as the Support Company behind them with 81mm mortars. In a stroke of luck our troops started the assault just as an RSAA platoon on trucks was moving up to the front line. These troops were soon driven to cover and their trucks destroyed but a hidden RSAA battery of 75mm howitzers inflicted casualties and knocked out an Argentine tank and the presence of the battery saved the town but C Company succeeded in occupying most of it and but losses on both sides prevented further gains until reinforcements arrived.
April 22
[A] 501 and 502 Regiments have captured New Blomfontein as RSAA troops fell back to another defensive line. Several FAA bomber raids in daylight have suffered heavy losses and fighter cover has been stretched to the limit allowing RSAF F-6B Swollow and bomber patrols to roam over eastern Argentina with little opposition and causing some disruption to rail and road traffic.
[S] After being repaired in a type 0 dock in Buenos Aires R13 returns to her Flotilla [Note]. Some tests have still to be run but she is otherwise battle worthy again.
[Note] Repairs have cost 23ts and are included in the SAEs April report.
April 24
[A] The General San Martin Squadron in a series of dogfights has shot down seven bombers and two fighters (F-3A Buzzards) over Encarnation as 2 and 9 Tabors resume the offensive and push the remnants of the 7th Zulu Regiment further north into a pincer movement by the 1st UPAF Brigade. This latter unit now supported by its own artillery has pushed north to meet a Brazilian spearhead. Along the river pocket I Division continues to attack as reinforcements from II Division become available.
April 25
[A] After the fall of New Blomfontein, A and C Companies of 501 Regiment at dawn attacked the outskirts of the small fishing village of Puerto Villegas Plata. This attack was on the northern flank of the village to cut off its roads and encircle the town for VI Division to reduce later as V Division continues its advance. A battery of 75mm field guns, a battery of Corps 155mm guns and a squadron (six tanks) of light T-1M31 tanks offered support. Army intelligence believes only one RSAA company was in the area supported by a handful of armoured cars of Great War vintage and field defences and naval gunfire (6 inch guns) from the harbour. The battle was in the words of one officer "a damn close run thing," but the entire northern flank had fallen and the road junction was in Argentine hands despite the strongpoint covering the western end of the town remaining intact. This part of the village was bypassed so RSAA forces within are now trapped. Vainly a new defensive line had been formed by RSAA forces but A Company still had enough spare squads left to continue the assault further. However Argentine forces have lost most of their heavy equipment and tanks. Some tank officers are complaining they do not have the right equipment for infantry support, the T-1M31 lacking firepower and thick enough armour for this role, and are suffering heavy casualties as a result.
April 27
[A] Another assault supported by thirty bombers and twenty fighters has attacked the northern flank of Mar del Plata and the temporary defence line has been breached. The local fighter airstrip used by F-3A and Type 14 fighters has been abandoned and around seven aircraft were destroyed on the ground.
[S] Light cruiser RSAN Iringa enters the yards in Durban for her class refit. Yard time will be four month until the ship will return to her unit for trials and active duty.
April 29
[A] The submarine Santa Rosa (P6) has been commissioned today. She is the last of the German P Type submarines planned for the Navy.
[S] De Graaf DB-1C Cutlass dive bombers from the carrier Gripper operating north of Ascension have sunk an Argentinean freighter on the Liberia - Argentina track trying to escape light cruiser RSAN Kimberley. The cruiser was send to investigate the ship after a scout plane on a recce mission reported a suspicious vessel.
[A] In Puerto Villegas Plata elements of V Division have broken through to the central area of the town but were repulsed from the harbour area and four Companies of RSAA troops trapped in the western half of the town have either fled back to rejoin their parent units now pulling back to the eastern side of the town or have surrendered.
A small counter-attack by RSAA troops supported by HCH-5R Hunchback light tanks and BT-5A Bullet fast tanks providing reconnaissance further inland led to a panic among some Argentine infantry units lacking anti-tank guns or tank support and a forward dump was overun and captured slowing V Divisions advance and forcing VI Division to cover the flanks and blunting their spearhead.
