Mit Blut und Eisen are rules for European style battles in the period 1840 - 1880.
Battles in the rest of the world can also be fought a long as the forces are similar to those used in Europe at the time. For example the American Civil War.
The focus of the rules is on the Crimean War (1853-56), the Franco-Austrian War of 1859, the American Civil War (1861-1865), the War of 1866 and the Franco-Prussian War of 1870-1871. Details of other conflicts during the period will be available later.
The rules are for large battles of this period.
The players will usually command a Corps or other large part of a full army, if not the whole army.
One base usually represents 600 infantry, 300 cavalry or 12 guns.
A unit is usually 3 to 12 bases and represents a brigade.
