Axis Diplomacy

Germany, Italy and Japan enter into a 10-year military and economic agreement. Also, the agreement promises that each will declare war on any third party which joins the war against one of the three. It is stated this agreement does not affect either Germany's or Japan's relations with the USSR. This treaty is known as the Tripartite Pact. All the signatories hope that the pact will deter the United States from joining the war in Europe or taking a more active line in the Far East. The agreement also recognizes the right of the Germans and the Italians to establish a 'new order' in Europe and the Japanese to impose theirs in Asia.

By signing the Tripartite Pact on 27 September 1940, Japan allied itself with the Axis Powers, Nazi Germany and Fascist Italy, in a partnership for world domination by military aggression.

Battle of Britain

Day 80

Weather - Fair across the south with occasional rain. Cloudy in the Channel.

Combat - The first large raid of the day appears at 0830hrs and consists of Me-109's and Me-110's. They sweep across the coast between Dover and Brighton and fly in split sections over the southeast, trying to encourage the R.A.F. fighters into battle. This duly happens and over the next hour, furious dogfights break out across Kent, Sussex, Surrey, London areas and north of London. In fact, an Me-110 is shot down by a Hurricane of No: 17 Squadron and crashes onto Duxford airfield. The fighting involves the Hurricanes of No: 17, 46, 73, 249, 253, 303 (Polish) and 501 Squadrons along with Spitfires of No: 64, 72, 92 and 602 Squadrons.

Meanwhile, at about 0900hrs, a small number of Ju-88's cross the coast of North Devon and are intercepted by Spitfires of No: 152 Squadron, scrambled from Warmwell.

As the first major attack subsides, another approaches the Kent and Sussex coast at 1130hrs and consists only of Do-17 and Ju-88 bombers. Fighter Command Squadrons are ripping into the helpless bombers as the Me-109 and Me-110 fighter escorts arrive. For nearly two hours aerial battles consume the skies over southern England involving the Hurricanes of No: 46, 229, 242, 249, 310 (Czech) and 501 Squadrons and the Spitfires of No: 19, 41, 66, 72, 92, 222, 602, 603 and 616 Squadrons.

As the raid over the southeast is developing, another approaches Dorset and attacks Filton at about 1130hrs. This raid is made up of Me-110's and Me-109's and are engaged by Spitfires of No: 152 and 609 Squadrons and Hurricanes of No: 56 and 504 Squadrons.

Just after 1500hrs, a third large raid consisting of Ju-88's and Me-109's is plotted approaching the coast between Dover and Brighton. They head straight for London and although intercepted by Hurricanes of No: 229, 249, 303 (Polish) and 501 Squadrons along with Spitfires of No: 19, 41, 66 and 92 Squadrons, many bombers make it through to central London to inflict heavy damage.

There are no further raids until during the night when the all too familiar pattern of bombing raids on London continue. Further raids are made against Liverpool, Edinburgh, Birmingham, Nottingham and the Bristol Channel area.

R.A.F. Losses: 45 aircraft damaged or destroyed, 18 pilots killed or missing and 7 wounded.

Luftwaffe Losses: 67 aircraft damaged or destroyed, 103 pilots and aircrew killed or missing and 12 wounded.

NOTE: Losses include non-combat patrols and accidents.
