French armistice negotiations prevented further operations; British bombers did not fly from France again until 1944.
Aftermath
In 2016, Greg Baughen wrote that after the loss of the Allied armies in northern France in May, Churchill accepted the view that such British military assistance available for France would be inadequate to influence the course of the campaign. Britain should send only the minimum consistent with boosting French morale. The effect of bombers on the ground battle was judged pointless, regardless of the example set by the and attacks on strategic targets were judged to be a better choice. Churchill insisted that once the German offensive began, the RAF should resume direct support of the Allied armies. The Chief of the Air Staff, Cyril Newall, gave an indication of British priorities when he claimed that the servicing units in France needed by any aircraft reinforcements were already committed to Haddock. Preparing a token effort against a hypothetical enemy, when the French were making a final effort to resist , the German offensive over the
