The yellow cake fleet has landed on the river, and they're waiting for it to clear up so they can go back to Kagoshima. They've got a bunch of photos of the fleet, so they'll be able to see what's going on. They don't want to be ambushed by the pro-fessor forces. They just want to get back to the city. They want to take a look at the river. They can't wait to get there. The retrieval unit has done a good job of capturing the fleet. They need to find a place big enough to land an aircraft. They also need a place to hide. They have to ambush the enemy forces to stop them from doing so.
