The Cuban-Haitian War was a gang war fought between the Los Cabrones and the Haitians in the events of Grand Theft Auto: Vice City. The participants of the war were Tommy Vercetti, Auntie Poulet, Umberto Robina, Pepe, and Rico.
The Start of the War
By the time Tommy Vercetti got into Vice City, a Haitian Ganglord was murdered, according to Avery Carrington. The Haitians believed a Cuban had murdered him but they had no proof to start the war in the first place. Avery Carrington needed to get hold of some land and asked Tommy to dress up as a Los Cabrone member and crash the ganglord's funeral and kill another ganglord in order to start the war between the 2 gangs. The Haitians quickly declared war on the Cubans and started attacking them. After the mission Tommy received a phone call by Umberto, who believed was talking to the recently killed Leo Teal at the beginning of the phone call but found out that Tommy had killed Leo and took his cell phone. Umberto was impressed and invited Tommy to a cafe that is owned by Umberto's father, Alberto Robina.
The Middle of the War
Umberto tested Tommy and he passed. Umberto quickly gave jobs to Tommy to weaken the Haitians. His first job was to steal a van filled with Drugs and take it back to the cafe. His next missions was to ambush a deal with Rico between the Haitians and the Sharks and take it back to cafe, but during the ambush Rico's boat blew up and Rico supposedly died but Tommy manages to bring the stuff back.
The Tables Turn
Tommy was asked to meet someone in Little Haiti which turned out to be Haitian leader Auntie Poulet but when Tommy got there he got brainwashed by Auntie with a mind-alterning drug and he did jobs against the Cubans without him remembering what he did. The first thing he did was use an RC plane and use it to blow up Cuban boats filled with drugs to turn the tables of the war. The final thing he did was to snipe Cuban members while they were in a fist fight with Haitian members. After what he "did" for the Haitians damaged his relationship with the Cubans and not only that but he was not permitted back to Little Haiti (of course you can come back but the the Haitians will shoot at you which could be a little annoying).
The End of the War
Angered for what they did, Tommy came back to the cafe to do one final job, to blow up the Haitian Drugs Factory. Tommy met up with Pepe and Rico, who supposedly survived the explosion, and attacked the the Drug Factory and successfully destroyed it making permanent enemies with the Haitians, forming an alliance with the Vercetti Gang and the Los Cabrones, and the Los Cabrones winning the war.
