Genesis

The Battle of Richmond, March 20, 1865: Captured by Confederate forces, the group escapes their captors and flees in a helium balloon. Rising into the sky, the travelers and their balloon are carried away by strong winds and soon find themselves over open water. Attempting to land, the balloon descends uncontrollably (helped along by Nemo observing from an island below) forcing the group to climb into the rigging and drop the backet to remain aloft in hopes of reaching the island before they plunge into the ocean. Struggling to stay in the air, Captain Harding sacrafices himself to the ocean, allowing the balloon to slow its descent and reach the island. Exploring the island for signs of civilization with Neb, Herbert becomes trapped in a rock pool as the tide comes, threatening to drown him. Neb manages to rescue Herbert (with unseen help from Nemo). Herbery and Neb enter into a cave where they encounter signs of habitation.
