Alcuesta was an imagi-nation South American campaign played many years ago with Mr M- S-. The campaign history dates from before I had access to the interwebs ,or possibly even to before they existed, so is old-school cut-and-paste. It's probably not quite as hilarious as I thought it was, but maybe you had to be there. 

One day I hope to get access to the superb multi-volume campaign history of the War of the Schwarzenstein Succession, the sole copy of which is currently held by the same Mr M- S-, and post it here. 

This is the whole history of the Alcuesta campaign, with the rules  at the back.
