The American air forces wound down operations in April 1945. Much of the bombing since the February attacks was tactical in nature, directed at almost any target that could be deemed an element of German resistance. Operation Clarion was carried out with mixed success against a range of smaller communications targets. On April 5 all objectives were defined henceforth as tactical, but American bombing of the shrinking German area reached a crescendo, with 46,628 tons dropped in nineteen days of raiding, almost the same weight dropped during the German Blitz, but in just three weeks.
