Pour the Cuban rum over ice in the highball glass and fill with Coca-Cola. Squeeze in a lime wedge.
Coca-Cola was only available in bottles for four years when the Rough Riders brought it along with them to Cuba. They mixed it with Cuban rum and lime and named it after their battle cry, "Cuba Libre." "Free Cuba" was the cry heard from the Rough Riders and their Cuban counterparts as they swept the Spanish out of Cuba.
