Ypiranga incident | Wikiwand

The Ypiranga Incident occurred on April 21, 1914, at the port of Veracruz in Mexico. The SS Ypiranga was a German steamer that was commissioned to transport arms and munitions to the Mexican federal government under Victoriano Huerta. The United States had placed Mexico under an arms embargo to stifle the flow of weaponry to the war-torn state, then in the throes of civil war, forcing Huerta's government to look to Europe for armaments.
