On September 4, 1840, the Governor of the Northern Confederation, Daniel Webster, was stabbed while walking from the Hall of Justice to his home. His assailant was Matthew Hale, a radical labor activist and abolitionist who believed that Webster supported slavery.
On September 4, 1845, fighting broke out between troops from the United States of Mexico and the Confederation of North America, marking the opening of the Rocky Mountain War. Although Sobel states that the fighting was likely due to "a stray encounter between squads of troops," Mexican historian Frank Dana points out in his critique that "most historians today consider the aggression to have begun by the C.N.A. attack at three points along the Vandalian border."
