London: The Blitz builds up. Chamber of House of Commons destroyed: MPs now meet in House of Lords. 20,000 Londoners killed and 25,000 badly wounded in war so far. Liverpool, Glasgow and Clydebank, Belfast, Southampton, Portsmouth and Plymouth all feel weight of Nazi attacks.

After last nights raids so many London streets are impassable - estimated at a third - that people can hardly struggle to work. Every main line railway terminus is out of action. Over 150,000 people are without gas, water or electricity. Pavements are littered with burnt-out incendiaries.

At least 5,000 houses have been destroyed. Estimates for last nights casualties are over 1,400 people dead and 1,800 badly injured. Rescue parties are still digging. Among the dead are the mayors of Westminster and Bermondsey. Many fires are still burning. There is huge gin fire in City Road and in the west the burning Palmolive soap factory is perfuming the air as the water directed on it turns into froth.

VICHY FRANCE: Darlan meets Hitler and declares resolve to enter war against Britain.

GERMANY: The Wehrmacht High Command announced:

Over the last few nights the British air force has once again deliberately bombed the residential districts of German cities, including the German capital. In retaliation, strong German Luftwaffe forces carried out a major assault on London last night. Ground visibility was good and the British capital was bombed throughout the night by relay waves that dropped high-explosive bombs of all calibres and tens of thousands of incendiary bombs.

MEDITERRANEAN SEA: Submarine HMS Undaunted sailed from Malta on 1 May for a patrol off Tripoli. She was due to return to Malta on 11 May but she failed to do so and is presumed lost on mines. It is also possible that she was sunk by the Italian torpedo boat Pegaso which had sailed from Tripoli on the 12th. At 2030 that evening Pegaso signalled that she had attacked a submarine with depth charges and that a large patch of oil had been observed, an indication of the submarines destruction. Against this theory is the fact that by that date Undaunted should have been back at Malta but it is possible that a decision to remain at sea longer had been taken or that she had suffered mechanical problems preventing her return. It is also possible that she was sunk by the Italian torpedo boat Pleiade off Tripoli on the 13th but this is not very likely.

LIBYA: Five Royal Navy destroyers bombard the harbour at Benghazi.

SYRIA: Two French Morane 406 fighter planes of 7 Squadron, 1st Fighter Group (GCI/7), forced 3 Me110's from 4 Squadron, 76 Destroyer Wing to land in the Syrian city of Palmyra because the German planes had crossed French territory without announcing their presence.

U.S.A.: Herbert Hoover, the former president, says that America must stay out of the war in order to help Britain.

ATLANTIC OCEAN: U110 sinks on tow to Iceland.

City of Shanghai (Master Arthur Frank Goring), dispersed on 28 April from Convoy OB-313, was spotted by U-103, but the lookouts of the vessel also spotted the U-boat and tried to escape. Schütze wrote in the KTB - Nun muss er fallen, wenn ich auch nur einen Aal im Rohr habe (Now he must fall, even if I have only one torpedo in my tube). At 0148 on 11 May, after a hunt of 19 hours, U-103 fired the last torpedo and hit the City of Shanghai, which was then finished off with the 105-mm gun off St Paul Rocks. Six crewmembers were lost. The master and 27 crewmembers were picked up by the Dutch merchant Stad Arnhem and landed at Freetown. 17 crewmembers were rescued by the British merchantman Richmond Castle and landed at Glasgow. 22 crewmembers were picked up by the Argentinian merchantman Josefina S and landed at Pernambuco.
