Camp Salubrity was established three miles west of Grand Ecore on the Texas Road May 18, 1844, where the fourth infantry companies were encamped. One of the young officers was Lieutenant U. S. Grant. On May 18, 1845, General Taylor at Fort Jesup received a letter marked “Confidential” from Secretary of War, Marcey. This secretly and officially marked the beginning of the disposition of troops and the laying of plans for the war with Mexico. Marcey wrote, “I am directed by the President to cause forces now under your command and those which may be assigned, to be put into position where they may most promptly act in the defense of Texas.” At Fort Jesup under the command of General Taylor were seven companies of the Second Dragoons and eight companies of the Fourth Infantry. Four companies of the Fourth Infantry were stationed at Camp Salubrity. Texas expressed a desire at the July 1845 session of the Texas Congress to become a State of the Union. General Taylor at Fort Jesup received instructions to place the Troops under his command in the Army of Observation in such locations that would be most advantageous to render support to Texas if such an occasion should arise. The Mexican conflict seemed inevitable and Taylor ordered Camp Salubrity abandoned and the Companies of Infantry there boarded steamboats at Grand Ecore for New Orleans along with three companies of the four companies of the 4th infantry which were stationed at Fort Jesup.
