Battle of Bouvines
In 1213, Salisbury led a large fleet to Flanders, where he seized or destroyed a good part of a French invasion fleet anchored at or near Damme. This ended the invasion threat but not the conflicts between England and France. In 1214, Salisbury was sent to help Otto IV of Germany, an English ally, who was invading France. Salisbury commanded the right wing of the army at their disastrous defeat in that year at the Battle of Bouvines, where he was captured.
