The thousand-bomber offensive was about to begin as Air-Marshall Harris was assembling his forces. Yet one man was to challenge his strategy. The aircraft designer Barnes Wallis thought: "What if there was a way to destroy Germany's industrial might not by simply dropping thousands of bombs over its cities, but by a precision strike against its dams?" For this, a new kind of bouncing bomb was to be delivered.

The Soviets have put civilians to work by the hundreds of thousands, building line after line of defenses in the Kursk Salient, where they are sure the Germans are soon to attack. Meanwhile the Allies are making moves in preparations for two big upcoming offensives of their own- in Sicily and the Central Solomon Islands.
