Lt. Piatt was sent with a letter to Nacogdoches, demanding that all Spanish patrols east of the Sabine River retire immediately to the west bank of that stream. Captain Edward D. Turner left for the Los Adais area with a detachment of soldiers on February 5, 1806. The Spanish patrol was contacted and Captain Turner delivered the ultimatum of Major Porter that it retire to the west bank of the Sabine River.[10] This document from the U. S. Army records shows the result of that meeting: The beginning of the Neutral Strip. At the Adais February 6, 1806. I, Joseph Maria Gonzalez, commandante of his most Catholic Majesty’s troops on this side of the Rio Sabinas, hereby having agreed with Captain Edward D. Turner, Captain in the United States Army, to return all troops of his Catholic Majesty’s to the other side of the said Rio Sabinas, as soon as my horses will permit it or in five days, or at the most six, and to make my march this day and I also oblige myself to not send any more patrols on this side of the Rio Sabinas. Signed: Ensign Joseph Maria Gonzalez Witness: John V. Duforest (Interpreter) The above document was the result of an agreement establishing a no-man’s land between the Arroyo Hondo and the Sabine River, which neither the United States Government nor the Mexican Government would use, until a final settlement could be reached between the two said governments about a boundary. This agreement was made by two young officers representing their respective countries, both willing to fight for their countries, but both having the intelligence and initiative to declare a stalemate to prevent a war. This forty mile wide strip of land became known as the Neutral Strip, and in it gathered the lawless of both countries. Even so, from within this lawless area were to come men who would strike the first blow for Texas independence. In 1807 several slaves of Louis Derbonne and other planters owning land adjoining the Neutral Strip, fled into the Neutral Strip and from there they went to Nacogdoches and on to Trinidad de Salcedo on the Trinity River, where they were given refuge by the Spanish Government. On September 5, 1807, Don Manuel de Salcedo, Governor of Texas at Nacogdoches, received a letter saying: The planters of the Natchitoches area are threatening to organize a force of 250 men to go after slaves known to be in the Texas area of Nacogdoches and at Trinidad de Salcedo unless the slaves are returned. The letter reminded the Spanish Governor of Article XX of the treaty between the United States and Mexico which said fugitive slaves must be returned to their owners. The letter was signed by Judge John Carr, and Justices Rouquier and Paillette.
