This week President Truman and his aides meet to discuss the use of the atomic bomb. In Japan, the imperial government vows to fight on even as Yokohama is turned to ash by firebombing. On Okinawa, Japanese 32nd Army withdraws from the defences of Shuri Castle but there is still plenty of hard fighting left for the Americans. There are US Navy command reshuffles and the stage is set for an Allied conference in Potsdam.

Now that Japan is the only Axis power still in the fight, Allied forces- especially American ones- must redeploy to prepare for the final invasion of the Japanese Home Islands. But how do you move millions of men halfway around the globe? And which ones go- veterans or new recruits, or some combination? Who decides? Where exactly do you send them to prepare too, with some many eastern ports like Manila a shambles? Let's take a look.
