* Anniversary of victory over Confederate invaders in 1856. William Walker was an American who planned to enslave Central American countries in the name of the Southern Confederacy. He had already taken over the Nicaraguan government in 1855 and declared himself president of that nation, and entered Costa Rica next. **The president of Costa Rica, Juan Rafael Mora, raised an army consisting mainly of farmers armed with machetes. They forced Walker and his troops back into Nicaragua. Walker was eventually caught and shot in Honduras in 1860 ***(thanks to shagtown.com)
