I do not intend this as a complete AAR, just thought it might be interesting to see how the Sea Lion scenario plays out, British player vs the AI. I'll make occasional posts as major events occur.
The scenario starts after a French landing at Hastings, with close to 300,000 men. The British have local garrisons scattered throughout the land, and a mobile force of close to 100,000 troops.
I decided to avoid a major battle, if possible. Perhaps even give up London, if the French directed their attentions there. I wanted to concentrate my forces, pull back, and hope to engage in battle against contingents of the French force - wear them down.
As the screenshots show, through turns 1-3 I was indeed able to concentrate my forces to the west of London, near Swindon. The French did not move from Hastings for those three turns.
Week four, Napoleon quick marched his forces directly towards Swindon, and forced me to fight. Fortunately for me, only a third of the French forces were able to enter the battle.
Still, it was a major loss for the British army, forcing a retreat towards Oxford.
