The provinces of New Granada had maintained independence from Spain since 1810, unlike neighboring Venezuela, where royalists and pro-independence forces had exchanged control of the region several times. To pacify Venezuela and to retake New Granada, Spain organized in 1815 the largest armed force it ever sent to the New World, consisting of 10,500 troops and nearly sixty ships. (See, Spanish reconquest of New Granada). Although this force was crucial in retaking a solidly pro-independence region like New Granada, its soldiers were eventually spread out throughout Venezuela, New Granada, Quito, and Peru and were lost to tropical diseases, diluting their impact on the war. More importantly, the majority of the royalist forces were composed, not of soldiers sent from the peninsula, but of Spanish Americans. Other Spanish Americans were moderates who decided to wait and see what would come out of the restoration of normalcy. In fact in areas of New Spain, Central America and Quito, governors found it expedient to leave the elected constitutional "ayuntamientos" in place for several years in order to prevent conflict with the local society. Liberals on both sides of the Atlantic, nevertheless, continued to conspire to bring back a constitutional monarchy, ultimately succeeding in 1820. The most dramatic example of transAtlantic collaboration is perhaps Francisco Javier Mina's expedition to Texas and northern Mexico in 1816 and 1817.
