bombarding Veracruz Three Navy rifle companies were instructed to capture the
customs house, post, and
telegraph offices, while the Marines went for the railroad terminal,
roundhouse, and yard, the cable office and the power plant. Arms were distributed to the population, who were largely untrained in the use of
bolt-action rifles like the German-made
Mausers and had trouble finding the correct
ammunition. In short, the defense of the city by its populace was hindered by the lack of central organization and a lack of adequate supplies. The defense of the city also included the release of the prisoners held at the "La Galera" military prison, not those at
San Juan de Ulúa (some of whom were political prisoners), who were later attended to by the US Navy. Although most of the regular troops retreated with Maass to
Tejería, the liberated prisoners under the command of Lt. Col. Manuel Contreras, and some civilians, opposed the Americans as they made their way to the
custom house. At 11:57, the Mexicans fired upon the Americans as they reached the intersection of Independencia and Emparán. The navy
signalman on top of the
Hotel Terminal, Capt. Rush's headquarters, was the first American casualty, and by the end of the day, 4 Americans were dead and 20 wounded. At 8:00 AM the next day, he gave orders to take control of the entire city. At 07:45 April 22, the advance began. The
leathernecks adapted to street fighting, which was a novelty to them. The sailors were less adept at this style of fighting. A regiment led by Navy Captain E. A. Anderson advanced on the Naval Academy in
parade-ground formation, making his men easy targets for the partisans barricaded inside. The cadets previously occupying the building had left Veracruz the night before after suffering casualties. This attack was initially repulsed; soon, the attack was renewed, with artillery support from three warships in the harbor,
Prairie, , and , that pounded the academy with their long guns for a few minutes, silencing all resistance. On April 26, Fletcher declared
martial law, and started turning the occupation over to the American army under the command of General
Frederick Funston. A third provisional regiment of Marines, assembled in
Philadelphia, arrived on May 1 under the command of Colonel
Littleton W. T. Waller, who assumed overall command of the brigade, by that time numbering some 3,141 officers and men. By then, the sailors and Marines of the Fleet had returned to their ships and an Army brigade had landed.
Resolution Marines and soldiers continued to garrison the city until the US withdrawal on November 23, which occurred after
Argentina,
Brazil, and
Chile became involved. Known as the
ABC countries, they were the most powerful and wealthy countries in South America at the time. They were able to settle the issues between the two nations at the
Niagara Falls peace conference. ==Political consequences==
