The Battle of the Ruhr or the Ruhr Air Offensive (March-July 1943) was a sustained bombing campaign by the British and the United States air forces against the industrial heartland of Germany during the Second World War (1939-45). The offensive included strikes against industrial cities and specific targets such as steelworks, armaments factories, transportation networks, and the Ruhr dams. Great damage was done to Germany's heavy industry, but given that production recovered and even increased, the battle is considered a draw.
