AT LAST THE U-BOAT MENACE HAD BEEN CONTAINED,

At last the U-boat menace had been contained, and no longer posed a threat to our very survival.  Germany had little left to fight with; only new boats and green crews, and few of these with the stomach for aggressive submarine combat.  Now attention shifted to the Mediterranean, Mussolini's "Mare Nostrum," and the next phase of the struggle against the Axis.  We will return to the Mediterranean theatre after a look at the developing war in the Pacific.
