#BattleOfBritain Parks tactics were to continually dispatch individual squadrons to intercept raids, to break up tight enemy formations

#BattleOfBritain Parks tactics were to break up enemy formations, then stragglers could be picked off one by one

#BattleOfBritain When multiple squadrons reached a raid, Park would send the slower Hurricanes to the bombers and Spitfires to the escort

#BattleOfBritain Keith Park ordered frontal attacks against bombers which were vulnerable to such attacks

#BattleOfBritain Leigh-Mallory of 12 Group proposed that at least three squadrons should be formed into Big Wings as pioneered by Bader

#BattleOfBritain Big Wing GOOD points: greater enemy losses, fewer own casualties

#BattleOfBritain Big Wing BAD points: too long to form up, greater risk of getting caught on ground refuelling

#BattleOfBritain Big Wing caused pilots to over-claim due to more confusing battle zone so thought to be more effective than reality

#BattleOfBritain Difference in the Parks tactics and Leigh-Mallory Big Wing caused a lot of friction between them

#BattleOfBritain Dowding wrote a report in November 1940: Big Wing resulted in just 10 interceptions and one German aircraft destroyed

#BattleOfBritain Post-war analysis agrees that Dowding and Parks approach was best for 11 Group as opposed to a Big Wing approach

#BattleOfBritain Dowding was removed from his post after the Battle of Britain for his lack of night fighter defence against Blitz

#BattleOfBritain Bomber Command and Coastal Command flew offensive sorties against Germany and France during the Battle

#BattleOfBritain Due to heavy RAF bomber losses before the Battle, it became clear that bombers would have to operate only at night

#BattleOfBritain From 15 May 1940 a night bomber campaign was launched against the German oil industry, communications and forest/crops

#BattleOfBritain Bomber Command changed its targeting priority on 2 June 1940 to attack the German aircraft industry

#BattleOfBritain On 4 July 1940 the Air Ministry gave Bomber Command orders to attack ports and shipping

#BattleOfBritain By September 1940 the build-up of German invasion barges in the Channel ports had become Bomber Commands top priority

#BattleOfBritain From 13-19 September Bomber Command sank almost 200 invasion barges contributing to Hitlers decision not to invade

#BattleOfBritain Bristol Blenheim units raided German-occupied airfields throughout July to December 1940 in night and day
