For Volley & Bayonet I use 2/3rds scale bases with 15mm figures. That means my bases are 2/3rds the size of the normal bases. Massed infantry and cavalry bases are 2″ x 2″ instead of the normal 3″ x 3″. Artillery and linear infantry are on 1″ x 2″ bases instead of 1.5″ x 3″. Finally AC and CC generals are on 1.5″ x 1.5″ bases and DC generals are on 1″ x 1″ bases. I do this for two reasons. First, I like to play on a smaller table. I’ve played a lot of games on 6′ x 9/12′ tables and they just seem a real chore to use effectively due to the depth and length. The smaller size bases allow me to play almost any ACW game on a 4′ x 6′ or 4′ x 8′ table. The second reason is that with professional/work and family obligations I don’t have the time to paint up thousands of figures, hundreds yes, but thousands no. So the smaller bases work well for me.
I tend to put 8 to 10 infantry on a massed base. For a massed cavalry or linear infantry base (dismounted cavalry) I put 4 figures on the base. For artillery units I put 2 gunners and 1 cannon on a base. DC commanders have 1 mounted officer and CC and AC commanders have 2 figures (at least one mounted) per base.
Here are some examples of my figures on the smaller bases. The figures come from a variety of makers: Old Glory, Minifigs, and Stone Mountain. Some were painted way back in 1982 and others were painted this year (hence the diversity in painting style and quality).
All of the figures are from my collection and Mark took all of the photos (some of which I think I made too light with the image auto correct!).
