I beat the peninsula campaign. Took a little under 10 hours and that’s with me personally fighting some battles I didn’t have to.
I never had more than 2 armies and a small force of guerrillas. I lost exactly one battle, were I had 400 of “armed citizens ” vs 4000 French regular.
I lost exactly 1 unit on the campaign, a 6pdr battery. Total losses probably around 1200 men, vs mabye 20 000 French.
