For Oshima is talking about two attacks. The first is a counterattack by Army Group G under Gen. Blaskowitz that is aimed at stopping and destroying the tankers in Patton’s Third Army and the combined forces in Devers’s Sixth Army Group. Without fuel and ammunition, which will have to be diverted to Montgomery, Blaskowitz’s attack will succeed. And if Montgomery fails in his attack—and he will fail, leaving his flanks exposed—then Eisenhower can foresee German Army Group G wheeling north and west to trap vast amounts of Allied soldiers and supplies.
