L12-G40 Mistergreen(axis) vs Shin Ji(allies)

[Shin Ji]

It's been pretty clear that I was going to lose for a while, but I don't see any rebound here at all.  Mistergreen, you are an amazing player, and you clearly deserve the win.

I'm trying to figure out my biggest mistakes here, besides trying to defend the UK navally instead of stacking infantry.  What would you say was my other big mistake, just so I can keep it in mind in the future?

[Mistergreen]

Thank you.  It was fun playing with you. 
I not sure you did another big mistake. Had sea lion not been an option things could have turned out differently with US annoying bomber campaign against Japan. 

I'm not really sure how to handle a sea lion. But I think I would have opted for a US fleet with more staying power.
