what was the result?
russian lost sub + cruiser + 3 ftrs, you lost 2 cruisers and 1 BB?
if this is the case, then you have cleared the seazone, and my procede to land. In the rules a clear seazone is defined as a seazone with only defending transports and submerged submarines.
if there are any planes left alive, they will shot at your transports. So if forex the situation is; you have 3 trannies, he has 1 ftr, then you can chose to retreat, you can HOWEVER not unload your transports in a friendly terr. (page 22 europe rule book)
it is also worth noticing that if a ftr can scramble against and amfibious assault even if there are no defending fleet. So you cannot only attack with transports, it was abit important when ussr could get NO for taking sardinia and sicily (then you could scramble with italian ftrs, prevening the landing no matter how many us ships was in the zone).
komiserik, you can retreat the transports, this is a seabattle, the amphibious assault is what happens IF you win the seabattle.
