Is a naval invasion of Petrograd a wise decision? It is April '17 in my game and I have been dithering with Russia far too long. Their NM is 37 and their PWR is 21/16. Although they have few forces, I feel to take a land route through Moscow and Petrograd is too late in my game -- I need a knockout blow, or at least something close to it - fast. I am pretty sure the garrison in Petrograd is not huge (not like Paris, where the WE can move troops in and out pretty easily). Rebel alignment is only 68 so I don't want to pin my hopes of eliminating Russia this way.
I know it is a risk, but is it advisable to attack Petrograd immediately from the sea with naval bombardment and distant unload with a strong army and risk elimination of my entire force if they don't get at least a beachhead? I am a little reluctant to invade an empty adjacent territory for fear that a bunch of reinforcements will make its way into the capitol the next turn, making a surprise invasion more difficult.
