President Johnson proclaims the U.S. will not honor Imperial Mexico's blockade of rebel Matamoras.

Emperor Maximilian of Mexico had ordered a blockade of the Mexican port city of Matamoras, just across the border from Brownsville, Texas, and then under the control of the rebel forces of Benito Juarez. Underlining the United States impatience with Imperial Mexico, President Johnson issued a proclamation stating in forceful terms that the United States would completely ignore this blockade. Any attempt, the document said, to enforce the blockade against American citizens "will be disallowed." (By John Osborne)
