Complete history of the late Mexican war/Battle of Matamoras
BATTLE OF MATAMORAS.
General Ampudia, who had superseded Arista, arrived from the South the 11th of April and ordered General Taylor to leave in 24 hours or he should consider us as having declared war against Mexico. Taylor answered that he did not wish for 24 hours but would return an answer at 10 o'clock the next day. He told Ampudia that he was sent there by his government in a peaceful attitude and he intended to remain, and warned Ampudia against firing the first gun. Lieutenant Porter, while out in pursuit of Col. Cross, who was supposed to be killed was attacked by some Mexicans and slain. Col. Cross was afterwards found murdered. April 26th an ambush was laid for a company of our men and 2 sergeants and 8 privates were killed in an engagement with the enemy.
There was every appearance of a general and speedy attack. General Taylor sent a requisition on the governors of Louisiana and Texas for 5000 men. April 25th General Arista arrived at the scene of action. April 28th Capt. Walker's camp was attacked by Generals Torrejon and Canales, being stationed midway between Point Isalel and Matamoras. 5 of his men were killed and 4 missing, he having gone out with some of his force on a scout. April 29th it was thought that the Point was attacked as cannon was heard in that direction, and a portion of the army marched immediately in that direction. The report was false as there had been no attack.
May 3rd the batteries from Matamoras opened upon our camp at day-break with great energy. The battle was fierce for a while and in 30 minutes all the heavy gun batteries of the enemy were silenced by our artillery. The enemy threw many shells; but without effect.
