Murmansk , Kola Fjord , Russia : 28 merchant ships out of 36 , from convoy PQ-16 arrived Murmansk
Baltic Sea : German cargo ship Orkan struc a mine and sank off Griefswald
Gazala , Libya : On 30 May, Rommel pulled the Afrikakorps back westward against the edge of the minefields, creating a defensive position in the Cauldron and puts up a defensive screen of anti tank guns (including dreaded 88 mm Flak guns) to protect his rear facing east , while he gathered and regrouped most of the striking power of Afrikakorps to the west to punch through enemy minefields and defensive boxes. A link was formed with elements of the Italian 20th Corps, which were clearing two routes through the minefields from the west. On the morning , German and Italian enginers reported that two lanes were cleared from British minefields between cornered Afrikakorps along Arierte Armored division trapped in Cauldron east of Gazala Laine in British rear and 21st Italian Corps west of Gazala line. However these lanes are still under British artillery fire. To get rid of that interferance Afrikakorps , 15th and 21st Panzer Divisions started a full scale attack on British 150th Infantry Brigade (from 50th British Infantry Division) defending Got Ul Utrieb box , to capture the box and re establish link with Panzer Army Afrika. Initial attacks of Afrikakorps to Got Ul Utrieb (Sidi Muftah box) were repulsed though by British infantry and anti tank guns. Rommel requests Luftwaffe to bomb Got Ul Utrieb box constantly.
Robert Lee, a member of the Royal Artillery, described his experience of a box on the Gazala line at the end of May 1942: âBoxes were originally to protect the Infantry. ⊠When youâre in an established position, theyâre like a camp. A huge area. Barbed wire all the way round the outside, then minefields with a gap, similar to a drawbridge. The tracks that go out from the box and then through the minefield are planted with mines each night. At dawn stand-to itâs the infantryâs job to go out and take up those mines and bring them back inside, all carefully accounted for. Then the OP Officer can ride out to his position. One morning they did a miscount. Left one on the track. Killed a troop commander. He drove into it. The men are arranged inside. The most vulnerable units are in the middle. ⊠Our system of boxes was essentially a defensive thing. It was too rigid. The boxes couldnât help one another. The Afrika Korps methods were more flexible. They could take each of our boxes in turn and have a battle with it. ⊠[As the situation deteriorated.] We held them off a long time. Getting on for four days and nights. Our guns were in action on 28th and 29th, plus the infantry â machine guns and mortar fire. Coming at us we had artillery shells, airburst rapid fire, machine-gun fire.â
The balance and disposition of the two armies meant that Rommel should have been on his knees before the superior might ranged against him; instead the flexibility, ferocity and discipline of his troops served yet again as a reminder of how he had earned his nickname: he was quicker, more imaginative, and more skilled in the deployment of his armour. Even in retreat, the Axis troops â Italian as well as German â displayed a sangfroid and expertise that forced Auchinleck to concede, âAlthough his lightning attack had failed, the enemy nevertheless gained a solid advantage.â
Describing one of the many confusing battles along the front, Auchinleck wrote with barely suppressed frustration of the way in which an entire Italian division (the Trieste) managed to escape through a British minefield (at Trigh Capuzzo) despite coming under heavy fire from Ritchieâs tanks. âOur armour strove to interpose itself between the enemy and the paths through the minefield,â he wrote, âbut he covered his retirement in characteristic fashion with a powerful anti-tank screen which our armour could neither penetrate nor outflank ⊠The whole of our armour was thus powerless to close on the gaps.â It was even worse than that. In the many weeks during which they constructed the chain of boxes along the Gazala front, the Eighth Army commanders had failed to ensure that the minefields strung between them were adequately covered from each box by artillery fire to pick off any enemy tank seeking to navigate the maze of buried explosives. The result of Ritchieâs oversight, as Auchinleck later confessed, was that after four days of sustained fighting, the panzers âhad succeeded in breaching our front and creating a dangerous salient in our main positionâ.
Mediterranean Sea : Royal Navy submarine HMS Proteus intercepted an Axis convoy made of three cargo ships , torpedoed and sank one of the Italian cargo ships , Bravo 70 miles west of Benghazi, Libya.
Cologne , Germany : By adding 367 training aircraft, British Air Marshal Harris managed to mount the first thousand-plane raid against Germany (the actual count was 1,046), Operation Millennium. Originally targeted for Hamburg, it was switched to Cologne due to weather. Over 1,400 tons of explosives were dropped on that city during the night of 30-31 May 1942, killing 500, injuring 5,000, and making nearly 60,000 homeless. 40 British bombers failed to return. The German government estimated that Cologne received 900 tons of high explosive and 110,000 incendiary bombs, and about 400 were killed.
This was the first time that the âbomber streamâ tactic was used and most of the tactics used in this raid remained the basis for standard Bomber Command operations for the next two years and some elements remained in use until the end of the war. It was expected that such a large number of bombers flying in a bomber stream through the Kammhuber line would overwhelm the German night fightersâ control system, keeping the number of bombers shot down to an acceptable proportion. The recent introduction of GEE allowed the bombers to fly a given route at a given time and height. The British night bombing campaign had been in operation for some months, and a statistical estimate could be made of the number of bombers likely to be lost to enemy night fighters and flak, and how many would be lost through collisions. Minimising the former demanded a densely packed stream, as the controllers of a night fighter flying a defensive âboxâ could only direct a maximum of six potential interceptions per hour, and the flak gunners could not concentrate on all the available targets at once. Earlier in the war four hours had been considered acceptable for a mission; for this raid all the bombers passed over Cologne and bombed in a window of 90 minutes, with the first having arrived at 00:47 of 31 May. It was anticipated that the concentration of bombing over such a short period would overwhelm the Cologne fire brigades and cause conflagrations similar to those inflicted on London by the Luftwaffe during the Blitz.
In the raid, 868 aircraft bombed the main target with 15 aircraft bombing other targets. The total tonnage of bombs dropped was 1,455 tons with two-thirds of that being incendiaries. Two and a half thousand separate fires were started with 1,700 classed by the German fire brigades as âlargeâ. The action of fire fighters and the width of the streets stopped the fires combining into a firestorm, but nonetheless most of the damage was done by fire and not directly by the explosive blasts. 3,330 non-residential buildings were destroyed, 2,090 seriously damaged and 7,420 lightly damaged, making a total of 12,840 buildings of which 2,560 were industrial or commercial buildings. Among the buildings classed as totally destroyed were: 7 official administration buildings, 14 public buildings, 7 banks, 9 hospitals, 17 churches, 16 schools, 4 university buildings, 10 postal and railway buildings, 10 buildings of historic interest, 2 newspaper offices, 4 hotels, 2 cinemas and 6 department stores. The only military installation damaged was the flak barracks. The damage to civilian homes, most of them apartments in larger buildings, was considerable: 13,010 destroyed, 6,360 seriously damaged, 22,270 lightly damaged.
âOf courseâ, Hermann Goering wrote in his diary, âthe effects of aerial warfare are terrible if one looks at individual cases, but one has to accept them.â âI hope you were pleased with our mass air attack on Cologne,â Churchill telegraphed to Roosevelt on the following day, and he added: âThere is plenty more to comeâŠ.â
The repercussions of the Cologne raid were considerable. In the Warsaw ghetto, the captive Jews rejoiced. âCologne was an advance paymentâ, Rabbi Emanuel Ringelblum noted in his diary a few months later, âon the vengeance that must and shall be taken on Hitlerâs Germany for the millions of Jews they have killed. So the Jewish population of tortured Europe considered Cologne its personal act of vengeance.â As for himself: âAfter the Cologne affair, I walked around in a good mood, feeling that, even if I should perish at their hands, my death is prepaid!â
The RAF lost 43 aircraft (German sources claimed 44), 3.9% of the 1,103 bombers sent on the raid. 22 aircraft were lost over or near Cologne, 16 shot down by flak, 4 by night fighters, 2 in a collision, and 2 Bristol Blenheim light bombers lost in attacks on night fighter airfields.
Berlin , Germany : Hitler spoke that day in Berlin to a group of recently commissioned German officers. âI do not doubt for a single secondâ, he told them, âthat we shall win in the end. Fate has not led me this far for nothing, from an unknown soldier to the FĂŒhrer of the German nation, and the FĂŒhrer of the German Army. She has not done this simply to mock at me and to snatch away at the last moment what had to be gained after so bitter a struggleâ. A thousand years earlier, Charlemagne had used harsh measures to create a German Empire; the German Army, Hitler warned, must now use harsh measures in the East if it were to win the space needed for the new German Empire to survive and flourish.
Hitler told Goebbels, as Goebbels noted in his diary next day on 31st May, âthat all restraint be dispensed with, and that the interests of the security of the Reich be placed above the interests of single individuals from whom we can expect little goodâ.
Inside Germany, and German-occupied Europe, it was the aftermath of Heydrichâs wounding during assasination attempt in Prague two days ago that was leading to âhell with interestâ. âHeydrich is in critical conditionâ, Goebbels noted in his diary on May 31. A âwhole crowd of Jewsâ, he wrote, had already been shot in Sachsenhausen concentration camp, and he added: âThe more of this filthy race we eliminate, the better things will be for the security of the Reich.â Two days later, a thousand Jews were deported from Vienna by train to Minsk; they were most probably taken on at once to Maly Trostenets extermination camp set up in German occupied Belarussia and their death.
Moscow , USSR : Soviet Premier Joseph Stalin finally approved the establishment of a Central Staff for Partisan Warfare under the direction of Byelorussian Communist Party Secretary Panteleimon Ponomarenko. The irregulars would now be organized along military lines with Red Army Commanders and NKVD officials to run them.
Madacascar , Indian Ocean : Before dawn, the floatplane of Japanese submarine I-10 conducted a reconnaissance mission over Diego-SuĂĄrez harbor, Madagascar, spotting British battleship HMS Ramillies, a tanker, a freighter, and an ammunition ship. At 1740 hours, I-16 and I-20 launched midget submarines M-16b and M-20b 10 miles from Diego-SuĂĄrez. M-20b fired her torpedo at 2025 hours, damaging HMS Ramillies and putting her out of action for a year. At 2120 hours, corvettes HMS Genista and HMS Thyme counterattacked with depth charges but failed to hit the Japanese midget submarines. Shortly after, M-20b fired her second torpedo, sinking British tanker British Loyalty.
Pacific Ocean : The Japanese intercepted, but could not decode, a report by USS Cuttlefish returning from patrol near Saipan, Mariana Islands. Around midnight, the Japanese Navy 6th (Submarine) Fleet at Kwajalein, Marshall Islands also reported monitoring messages exchanged by two American task groups located 170 miles north-northeast of Midway Atoll, moving westwards.
Aboard battleship Yamato, Admiral Yamamoto suggested that the information be relayed to the First Air Fleet flagship carrier Akagi, but senior staff officer Captain Kuroshima cautioned not to break radio silence. In any case due to radio malfunction of wireless sets in Akagi , First Carrier Division heads towards Midway under total communication blackout.
Elsewhere, the transport fleet of the Japanese Aleutian invasion fleet set sail from the main island of Honshu of the Japanese home islands; it was consisted of 8 transports. In the northern Pacific Ocean, Japanese submarine I-25 surfaced for the launching of her floatplane for a reconnaissance missiong over Dutch Harbor in the Aleutian Islands; an American cruiser sailed near by luck but failed to spot the submarine; I-25 would continue with the reconnaissance mission after a short while.
American submarine USS Pompano torpedoed and sank Japanese troop transport Atsuta Maru 80 miles east of Okinawa, Japan.
Pearl Harbour , Hawaii : USS Yorktown, having received rushed repairs from 1,400 dock workers within 45 hours after her arrival and still two boilers damaged and non operational (thus reduced speed) , departed Pearl Harbor, US Territory of Hawaii alng with her escorts , heading for Midway Atoll.
