Operation Cobra is the drop that finally opens the floodgates and the Allies make a breakthrough in Normandy; up in the Baltics the Soviets take Shaulyai, Dvinsk, and finally Narva, though their big prize this week is Lvov further south. This happens during the Poles' Lvov Uprising, which ends badly for the Poles. Things also go badly for the Japanese on Guam, though, as their assault this week devastates their own troops.
