Thanks! I think putting the leadership into officer training (combined with the tons of experience my generals have gained) have enabled me to roll over the French. Manpower is becoming an issue. I won't run out, but it'll be a while before I can build a lot more troops. Thankfully, I have other places to put the IC (like rebuilding the navy).
Indeed, you'll need rebuild your fleet and soon. Although you'll not be able to outfight the British at sea, they'll have to stop you from getting just one load of troops ashore in Britain.
Another idea might be to upgrade your troops (ie Mountaineers) or to reorganise your forces (2x Inf 2x support per division).
