Alternative Chacabuco – A March Attack Scenario

The Liberators supplement (Fletcher, 2006, p. 10-11) has an Alternative Chacabuco scenario. These are my notes for playing the scenario with the March Attack. See also the Battle Report.


Setting: Chacabuco Farm, Chile; 13 Feb 1817

This scenario poses a What-if. The premise is that after crossing the Andes from Argentina, the patriot army advances more cautiously giving the royalists time to bring up reinforcements from Santiago.


  • Use the map in the published scenario.
  • You’ll have change the ground scale of the rules (1 inch = 60 yards) to match the map (1 inch = 40 yards)
  • Talhuilaca Hill is steep and has two levels
  • Los Tauretes Hill is steep with only one level
  • The small hill is gentle with one level.
  • The fields all count as rough ground.
  • The vineyard is an orchard
  • The farm is a light BUA.

Victory Conditions

Normal March Attack victory based on Major Formation and Army Morale.

Scenario Special Rules

The scenario uses a ground scale of 1 inch is 40 yards. March Attack assumes 1 inch is 60 yards. So I increased all distances (ranges and movement) by 50% (rounded up). For example, Engagement distance is normally 9 inches but I made it 14 inches.

My Liberators cavalry are based as single stand squadrons but March Attack has two stand regiments. I could have combined the squadrons into two stand units but instead chose to run them as single stand units in Line.

For this game I ignored the skirmisher rules of March Attack. Needs a bit more thought.


  • The Orders of Battle retain the “Sk” and “s” annotations for skirmish capability of the original army lists. This is until I figure out what to do with skirmishers in March Attack.
