The information for 1760 is drawn from the Memorias de los virreyes, IV, 274-275, 283-284. The figures for the fixed and veteran troops include deserters, sick or retired personnel, recruits, and sometimes even Indian auxiliaries. They should therefore be considered as available, rather than effective, troop strength.

This figure includes the 156 soldiers detached in Tarma and the sixty-seven detached in Jauja as well as soldiers temporarily detached to the presidios of Chile.

The information for 1776 represents a composite of the following sources: Compendio de las Prevenciones que el Exelentísimo Senor Don Manuel de Amat hizo para la defensa de la Guerra contra Portugal, e Inglaterra, Lima, Nov. 10, 1763, 23 ff. AGI, Lima 1490; Memoria de Amat, pp. 706-731; Sáenz-Rico Urbina, El virrey Amat, I, 221-234; and Guillermo Céspedes del Castillo, Lima y Buenos Aires (Seville, 1947), pp. 85-86.

This figure reflects fixed and veteran troops detached on the islands of Chiloé and Juan Fernández and in the interior garrisons of Tarma and Jauja, as well as a small detachment of training officers from the Regiment of Infantry of Portugal which served as a command and staff group for the militia after 1770. Not included in this figure are about 200 officers and sailors of the Royal Navy serving aboard warships at Callao.

The exact strength of the Army of Peru at any given time is difficult to determine. Amat’s figures were based on a series of incomplete reports which did not include nine provinces out of the seventy-nine then existing in the viceroyalty, I have attempted to estimate the strength of the army in these unreported areas in order to provide a more exact figure although subsequent status of forces reports make it quite clear that total military strength was far below whatever estimates were made at the time. About 60,000 soldiers were classified as infantry, 22,000 as cavalry, and 13,000 as dragoons, or mounted infantrymen.
