Within several days after Gillmore's departure, Seymour's confidence about the expedition seems to have returned. Seymour informed his superior that he now intended to advance to the Suwannee River to destroy the railroad bridge there. "By the time you receive this I shall be in motion," he declared to his shocked superior. Gillmore dispatched an officer to stop Seymour, but the Battle of Olustee occurred before he reached Florida. It is not known exactly why Seymour suddenly reached the decision to advance, but by February 19 he had assembled his troops at Barbers in preparation for a movement westward the next day.
