Alternative Chacabuco – A Lasalle Scenario

Francisco of Argentina and Texas has done some thinking about Lasalle for South American War of Independence. He calls the variant “Necoechea” after a renowned Argentine cavalry commander of the war. One of the first things Francisco tried was a variant of Chacabuco. I have fairly cheekily reproduced it here. Note: this is not the same “Alternative Chacabuco” that John Fletcher published.

Historical Situation

Setting: Chacabuco, Chile; 12 Feb 1817

The battle is based on a what if scenario for the battle of Chacabuco. San Martin finished crossing the Andes with his army early in 1817, and in a fast action managed to engage and defeat a royalist army on Feb 12 before they could even be reinforced.

In this scenario we assume that the patriot army advances more cautiously giving the royalists time to bring reinforcements. The battle takes places in the surroundings of the Chacabuco farm ( instead of the original battlefield, slightly to the north).

The patriots advance on the farm in two divisions just as the royalists are about to take positions to await reinforcements from Santiago de Chile.

The patriot army took the role of attacker and the royalist took the role of defender ( the royalist chose the side of the table and deployed first). I did my best to get armies that would seem balanced.


Note from Steven: It is obvious from the photo that Francisco didn’t use the map from John Fletcher’s book. In fact he set up a balanced table then let the royalist chose the side of the table on which to deploy. The Patriots deployed on the other sdie.
