Now that the war within our borders is over, we must turn our attention to the European intervention into the affairs of Mexico. Gen. Sheridan reported that Kirby Smith had sold his arms to pro-French forces. I wrote Sheridan,
WASHINGTON, June 15, 1865 – 1. 30 p. m.
New Orleans, La.:
Demand of the commander of French forces at Matamoras the delivery to an officer of the Government of the United States the return of all arms and other munitions of war taken to Matamoras by the rebels or obtained from them since the date of the surrender of Kirby Smith. You need not proceed to hostilities to obtain them, but report the reply received for further instructions.
