The Battle of Britain Five Months That Changed History, May—October 1940 by James Holland (z-lib.org).epub

He was determined to cross at Sedan, a place he knew intimately from
when he had been stationed there during its German occupation in the last
war. Von Kleist, however, demanded that Guderian’s divisions should cross
at Flize, some eight miles west of Sedan. There were good arguments for
both sites, but Guderian resolved this spat by simply ignoring his superior –
a high-risk strategy should his crossing attempt fail. But there was less he
could do about von Kleist’s interference with the Luftwaffe support
promised. Guderian had acted entirely autonomously, going straight to
Generalleutnant Bruno Loerzer, Göring’s old First World War flying chum
and now commander of VIII Fliegerkorps in Luftflotte 3 to ask for air
support. His big problem was a lack of artillery, most of which was still
struggling its way through the Ardennes. The Luftwaffe could do the
artillery job for him, however. Drafting a carefully prepared fire plan, he
asked Loerzer to hit these targets with a kind of rolling aerial barrage of
wave after wave of Stukas and bombers. The aim was to stun the French by
near-constant attacks.
