Let's start with the rules.
I've heard a lot of good things about "Went Well the Day?" which is a platoon scaled game for fighting Very British Civil War actions. War Plan Red is set in the same time period using the same technology and equipment. Also, I get the feeling that the forces involved in this War of 1812, part 2 have the possibility of having the same quirkiness that VBCW forces have. Plus the rules just sound fun to play! Here's a video review of the rules.
Next let's look at the infantry that I'll be using for the British forces. There are a lot of possibilities out there ranging from WWI Tommies to WWII BEF. So after much hemming and hawing I've decided to go with the Battlefront BEF troopers, but with some reservations.
I've seen these guys up close and they do look good painted up. However I'm a little put off by the length of the Enfield rifles. Those rifles carried by the BEF models look too short to me. But looking at other pictures make me wonder...
Anyway, at less than $20, including shipping, I was able to get a full platoon with three rifle sections, a 2' mortar, and a Boys anti-tank rifle. Not a bad deal really! It's a full "force" for WWtD and has a nice and accurate mix of weapons. Now I just need some Universal/Bren carriers and perhaps a I-tank or so and my British force is ready to be painted and fielded.
