For the liberals, a metaphor:

It's the end of the American Civil War. The Southern lines have collapsed, the Union is surging. Robert E Lee and the remaining confederates, rather than surrender, decide to retreat to the island of Puerto Rico. The US Army moves to pursue them, but Spain sends an armada to point it's guns at Florida.

Once ensconced on Puerto Rico, the slavers initiate a brutal anti-abolitionist crackdown that sees them murder tens of thousands of people. Then they proceed to implement four decades of martial law and throw at least 140,000 people into concentration camps on suspicion of being "yankee sympathizers". Thousands more are disappeared into the jungle by the Dixie death squads.

Meanwhile, Spain floods Europe with propaganda about the noble freedom fighters of Puerto Rico and their valiant struggle against Northern Aggression. To this day, the face of Robert E "Memphis Massacre" Lee is stamped on the money.
