After France fell to the Nazis in 1940, Vichy French naval troops were blockaded on Martinique. Forced to remain on the island, French sailors took over the government from the Martiniquan people and established a collaborationist Vichy regime. In the face of economic distress and isolation under the blockade, they instituted an oppressive regime; Fanon described them as taking off their masks and behaving like "authentic racists". Residents made many complaints of harassment and sexual misconduct by the sailors. The abuse of the Martiniquan people by the French Navy influenced Fanon, reinforcing his feelings of alienation and his disgust with colonial racism. At the age of seventeen, Fanon fled the island as a "dissident" (a term used for Frenchmen joining Gaullist forces), traveling to Dominica to join the Free French Forces.
