But obviously the chief business of the government was the negotiation with Trist. Here Santa Anna acted sincerely--as sincerely as the drowning man who clutches at a plank, no matter how great a rascal he has been. On this point we have a superabundant amount of evidence, and in particular the full reports of Lozano, chargé d'affaires of Spain, with whom Santa Anna talked explicitly and at great length. Texas and upper California could be given up, the General thought, as territory already lost. The region between the Rio Grande and the Nueces, it was hastily inferred from a vague remark dropped by Trist at Puebla, could be made neutral, perhaps under a European guaranty; and with that barrier established against smuggling and the dreaded encroachments of the United States, and with millions of shining American dollars pouring into the treasury for the benefit of those supporting him and the treaty, Santa Anna felt he could meet all opponents. In his own mind, though he intended to get still better terms if possible, the bargain was as good as made. He therefore placed on the commission superior men, disposed to effect an amicable settlement, and not mere partisans of his own: ex-President Herrera, J. B. Couto, a man of the highest integrity and leader of the Mexican bar, General Ignacio Mora, chief of the military engineers, and Miguel Atristain, a lawyer supposed to represent British commercial interests; and he put forth a manifesto entirely satisfactory from the American point of view, in which he declared openly for peace, and, holding that Congress on being duly consulted had referred the subject back to the Executive, brushed aside the law of April 20.[27.17]
