 Such an approach may have provided maximum effectiveness at the beginning of a war, but it effectively mortgaged the Luftwaffe's future.Hermann Plocher, chief of the operations staff, urged Jeschonnek to reconsider and prepare for a long war but his superior rejected the warning.Specifically, Plocher warned Jeschonnek on the need for a prompt build-up of reserves in both flying personnel and aircraft, insisting that only by a continuous flow of reinforcements through training and further production could the losses that were to be expected in case of war be made good to some extent, so that the operational strength of the units would not drop too quickly below an irreducible minimum.
