From Grant’s Memoirs
Before I returned I mustered up courage to make known, in the most awkward manner imaginable, the discovery I had made on learning that the 4th Infantry had been ordered away from Jefferson Barracks. The young lady afterwards admitted that she too, although until then she had never looked upon me other than as a visitor whose company was agreeable to her, had experienced a depression of spirits she could not account for when the regiment left. Before separating it was definitely understood that at a convenient time we would join our fortunes, and not let the removal of a regiment trouble us. This was in May, 1844. It was the 22d of August, 1848, before the fulfillment of this agreement. My duties kept me on the frontier of Louisiana with the Army of Observation during the pendency of Annexation; and afterwards I was absent through the war with Mexico, provoked by the action of the army, if not by the annexation itself. During the time there was a constant correspondence between Miss Dent and myself, but we only met once in the period of four years and three months. In May, 1845, I procured a leave for twenty days, visited St. Louis, and obtained the consent of the parents for the union, which had not been asked for before.
