On this day 250 years ago, a Spanish officer at Arkansas Post reported to another Spanish official that a Quapaw chief had been visiting the British in Pensacola. The Spanish were concerned because the Quapaw had been long allied with the French in Louisiana in warfare against the British and the Spanish had expected to retain the Quapaw as allies when they succeeded the French in control of Lousiana. In the final years of the Revolution this alliance would be critical for the Spanish when they entered the War against the British.
