Fort Webster was an outpost established in western Vandalia by the North American Army during the Rocky Mountain War. It was named after the late Governor of the Northern Confederation, Daniel Webster.
The fort served as a base of operations for General Philip Lodge's successive invasions of Mexico del Norte from 1846 to 1848. General David Homer's army set out from Fort Webster in March 1849. It was initially assumed that he, like Lodge, intended to attack the Norteño capital of Conyers, but instead Homer led his army west into Arizona, with the ultimate aim of taking the Californian capital of San Francisco. When it was learned that Homer's army was in danger of being trapped in Williams Pass, California, a force of Southern Confederation militia under General FitzJohn Smithers set out from Fort Webster in the summer of 1850 in a desperate attempt to rescue Homer's men. In the end, both North American armies, along with two Mexican armies, took part in the Battle of Williams Pass, which left them all trapped in the pass over the winter of 1850-51, during which time most of the men on both sides perished of cold and starvation.
It is not known which confederation Fort Webster was located in after the division of Vandalia into Northern and Southern Vandalia in 1877.
