Hi,

My brother bought me a copy of AAE for Christmas, so I’m new to the game.  We have argued over the Submerging Sub rule.  My take is that a defending sub can only submerge after it has been attacked.  If it survives then it may submerge instead of returning fire.  He seems to think that a sub has the choice to stand and fight, or submerge.  This all came about after an American fleet (2 destroyers and a Battleship) attacked a single U-boat.
I have quoted many of the other threads on the submerging rule, be my brother insists that none of the previous explanations are clear!

Please someone spell it out for me.  Does the defending sub have the option to stand and fight or submerge, before being attacked?
