Beginning in late December 1778, the British captured Savannah and controlled the Georgia coastline. In 1780 they seized Charleston, capturing a large American army. A significant victory at the Battle of Camden meant that royal forces soon controlled most of Georgia and South Carolina. The British set up a network of forts inland, expecting the Loyalists would rally to the flag. Far too few Loyalists turned out, however, and the British had to fight their way north into North Carolina and Virginia with a severely weakened army. Behind them most of the territory they had already captured dissolved into a chaotic guerrilla war, fought predominantly between bands of Loyalist and Patriot militia, with the Patriots retaking the areas the British had previously gained.
