16-17 May
A
force of 19 specially modified Avro Lancasters of No.617 Squadron, RAF
Bomber Command, led by the squadron commander Wing Commander Guy Gibson,
attack a series of dams in the Ruhr Valley using Upkeep rotating mines
designed by Barnes Wallis.
Only twelve Lancasters reach the target area.
One is forced to return after flying so low that it strikes the sea, which
tears away the Upkeep bomb. Five are shot down by enemy Flak (anti-aircraft
fire) and one is so badly damaged by Flak that it is forced to turn back.![]()
Five of the twelve surviving Lancasters, led by Wing Commander Gibson, attack and breach the Möhne Dam and a further three attack the Eder Dam, which is also breached. Of the remaining aircraft, three attacked the Sorpe Dam and one the Schwelme Dam, neither of which are breached, and one fails to find its target in misty conditions and returns without releasing its bomb. Three further Lancasters are lost after they release their weapons. 53 aircrew are killed and three captured.
The
raid is a significant success, creating widespread flooding. Wing Commander
Gibson is subsequently awarded the Victoria Cross, having delivered his
attack with great accuracy and afterwards circling very low for half an
hour, drawing the enemy fire to his aircraft to clear the way for the
attacks that follow. 34 other aircrew from the squadron are also decorated.
23-24 May
During a heavy raid on Dortmund, the total weight of bombs dropped by

Sir Arthur Harris, sends this message, "In 1939, Göring promised
that not a single enemy bomb would reach the Ruhr. Congratulations on
having delivered the first 100,000 tons of bombs on Germany to refute
him".

A Short Sunderland of No.464 Squadron, Royal Australian Air Force is attacked
over the Bay of Biscay by eight Junkers Ju88s. The ensuing combat last
for 45 minutes and sees the Sunderland shoot down three of the attacking
Ju88s. The Sunderland is badly damaged, with one of its crew killed and
three wounded. Nevertheless, the pilot, Flight Lieutenant C.B. Walker
brings the aircraft safely back and is subsequently awarded the Distinguished
Service Order.
The combat indicated the seriousness with which the Germans viewed the Allied air threat to their U-boats transiting the Bay of Biscay from their French coastal ports. The Germans deployed long range Junkers Ju88s of Kampfgeschwader 40 and shorter ranged Focke Wulf Fw190 fighters to try to combat the threat of Allied aircraft. In response the Royal Air Force (RAF) deployed Bristol Beaufighter and later de Havilland Mosquito squadrons to try to counter the threat of German interceptors. The patrols became known as Instep operations. The RAF lost 15 aircraft in patrols over the Bay of Biscay during June 1943. 4 Junkers Ju88s were claimed as destroyed by Instep patrols.

9-10 July
The
invasion of Sicily (Operation Husky) opens with an airborne assault mounted
from airfields in North Africa. United States Army Air Force (USAAF) and
Royal Air Force transport aircraft tow in the gliders (sailplanes) of
the 1st British Airborne Division and drop the paratroops of the US 82nd
Airborne Division.![]()
Poor weather, combined with the inexperience of many of the USAAF transport aircraft crews that participate in the operation, results in only 250 of the 3,000 US paratroops reaching designated drop zones.
The
1st Airborne Division's air landing fare even worse, as 69 out of the
137 gliders released land in the rough seas, drowning large numbers of
men. Only twelve gliders, all towed by RAF aircraft with crews better
versed in night operations, reach the correct landing zones. Fortunately
the sea-borne landing fared rather better.![]()
