In response to the Tampico Affair, President Woodrow Wilson ordered the U.S. Navy to prepare for the occupation of the port of Veracruz. While waiting for authorization of Congress to carry out such action, Wilson was alerted to a German delivery of weapons for Victoriano Huerta due to arrive to the port on April 21. As a result, Wilson issued an immediate order to seize the port's customs office and confiscate the weaponry.
