The Battle of Mollwitz was fought by Prussia and Austria on April 10, 1741, during the early stages of the War of the Austrian Succession. It was the first battle of the new Prussian King Frederick II, in which both sides made numerous military blunders but Frederick the Great still managed to attain victory. This battle cemented his authority over the newly conquered territory of Silesia and gave him valuable military experience.

The Boardgaming Life Blog has recently reviewed a very simple war-game for beginners set around this battle, and despite poor graphics it’s worth having a look to get a sense of how to initiate beginners to wargames. The game can be downloaded as a free PDF here.
A very nice exercise from the Author, Chris Salander, inspired from a card game on the Battle of Hohenfriedberg. I found the original and very ugly graphics, as well as a nicer variant on the Cartographers Guild site. A very good example on how the game experience can be dramatically enhanced with just the right visual assets.
