			  | Backing up a few days, on February 11th I landed 3 Marine and 3 Army divisions each at Chiba and Utsonamiya. Both hexes are adjacent to Tokyo. On the 12th both objectives fell to the initial assaults. In addition, the Soviet 2nd Red Banner Army is adjacent to Utsonamiya ready to advance into Tokyo. The First Red Banner Army has invested Sendai. The 6th Guards Tank Armay and 17th Army overran northern Honshu. The NorPac invasion of Hokkaido is loaded and underway toward the beach at Bihoro, with a Soviet Army ready to follow.
