The Patriot flags seemed to be in a state of flux during the 1817-18 Chilean Campaign so I thought I’d summarise the various bits of information. For reasons outlined below this is my best guess for which flag for which unit at which battle.
1818 Maipo
At the Battle of Maipo (5 April 1818), fought near Santiago, Chile, the Patriot Army of the Andes led by Argentine general José de San Martín effectively destroyed the Royalist forces in Chile commanded by General Mariano Osorio. Note: Maipo is often spelt Maipú.

Phase 4 of my 1817-18 Chilean Project is the Battle of Maipo (5 Apr 1818).
Patriot Cazadores a Caballo in the 1817-18 Chilean Campaign
The various sources are inconsistent about the Argentine and Chilean Cazadores a Caballo in the 1817-18 Chilean Campaign. In a discussion on the Liberators 1810-1830 Yahoo Discussion Forum, John Fletcher expressed the opinion that all references to Argentine Cazadores a Caballo and Escolta del General were in fact the Cazadores a Caballo de la Escolta del General. Similarly references to Chilean Cazadores a Caballo, Chilean Horse Cazadores or Chilean Escort Cazadores, are the Caballeria Cazadores de la Escolta Directorial. He recommended getting two squadrons of each unit for the Chilean campaign.
