Joseph Schmid, the OKL's chief intelligence officer, was primarily responsible for providing inaccurate and distorted information to senior German air commanders encouraging enormous over-confidence. The Luftwaffe regrouped after the Battle of France into three Luftflotten (Air Fleets) . Luftflotte 2, commanded by Generalfeldmarschall Albert Kesselring, Luftflotte 5, led by Generaloberst Hans-Jürgen Stumpff was based in Norway and Luftflotte 3, under Generalfeldmarschall Sperrle. Luftflotte 2, whose units were based in northern Germany, Netherlands, Belgium and France north of the Seine, would be concerned mainly with the area east of a line from Le Havre through Selsey Bill to the Midlands; Luftflotte 3, based in western France, would deal similarly with objectives west and north-west of that line. Each Luftflotte was to attack shipping off its own stretch of coast. Diversionary attacks, intended to draw off part of the defences from the south, would be made on north-east England, south-east Scotland and shipping in adjacent waters by Luftflotte 5 from Norwegian and Danish airfields. Kesselring was responsible for all air force units in northern Germany, Netherlands, Belgium and north-eastern France while Sperrle was in control of forces in northern and western France. Luftflotte 3 was assigned Alfred Keller's Fliegerkorps IV, based in Brittany, Richthofen's Fliegerkorps VIII in the Cherbourg region, and Greim's Fliegerkorps V in the Seine area—precise boundaries between the air corps are not known. The entire bomber strength of Sperrle's air fleet was reserved for night bombing. Sperrle's command did not begin large-scale daylight attacks until the last week of September. Sperrle's first task against the British Isles was during the Kanalkampf (Channel Battle) phase of what became known as the Battle of Britain. The aim was to draw out Fighter Command into dogfights by attacking Channel Shipping. Targeting British convoy systems, in July 1940 Sperrle's air fleet claimed 90 vessels sunk for approximately 300,000 tons—a third of this was claimed over August and September. The claims were widely optimistic. Only 35 ships were sunk during the Kanalkampf period. Sperrle was becoming disconcerted at the personnel, rather than aircraft, losses. Two days before Operation Eagle—scheduled for 13 August—he had lost two Gruppenkommandeur and a Staffelkapitän. Sperrle knew he could not afford to lose experienced officers at such a rate. The emphasis of German air attacks switched to bombing Fighter Command bases and its infrastructure. On 13 August 1940, Sperrle's air fleet played a role in the failed Unternehmen Adlerangriff ("Operation
