Air Operations, Europe

• 24 Venturas bomb railway targets at Abbeville and Caen, but most of the bombs miss their targets. There are no losses.

• 208 Lancasters and 3 Halifaxes bomb the dock area at La Spezia and cause heavy damage. 4 Lancasters are lost and 3 more, either because of damage or technical difficulties, fly on to recently captured North African airfields. It is believed that this is the first time this has occurred. The 3 Lancasters later fly back to England.

Damage to the docks at La Spezia; 2 fires (1 and 2) continue to burn while a large store has been completely gutted (3).

Damage at La Spezia

• 6 Mosquitos of No. 105 Squadron carry out nuisance raids to Bremen, Hamburg and Wlhelmshaven, 2 planes to each target. These are the first non-Oboe Mosquito night raids and are the forerunners of Light Night Striking Force operations. The Germans hate the nuisance and harassing effect of the Mosquito raids and rarely shoot down any of these fast, high-flying aircraft.

• 10 Lancasters lay mines off Germany and there are 18 OTU sorties.
• 1 OTU Wellington is lost in the sea.

This pattern of anti-aircraft fire provides a protective screen over Algiers at night. This photo, recording several moments of gunfire, shows a defense thrown up during an Axis raid upon Algiers in North Africa 13 April 1943.

Anti-Aircraft Fire over Algiers

North Africa

In the British 8th Army area, advance elements of the X Corps, continuing northward along the coast, reach an anti-tank ditch guarding the enemy's next delaying position at Enfidaville. Subsequent efforts, on a limited scale, to force the enemy from his Enfidaville position before it can be strengthened are futile.

Not Quite Asleep In The Deep

Occupied Soviet Union

Radio Berlin announces the discovery of a mass grave (at the Russian forest village of Katyn) or 4,500 Polish officers who have been murdered, it claimes, by the Soviet NKVD. The Soviet Government responds two days later, counter-charging that the Germans have killed the Poles. On April 23, 1943, Churchill will assure Soviet Ambassador Maisky in London: 'We shall certainly oppose vigorously any investigation by the International Red Cross or any other body in any territory under German authority. Such investigation would be a fraud and its conclusions reached by terrorism.' (The Russians will in November 1989 admit responsibility for the Katyn shootings.)
