British and Commonwealth forces fought the neighboring Italians during the East African Campaign.  In 1941, the Italians were defeated and the Vichy forces in French Somaliland were isolated. The Vichy French administration continued to hold out in the colony for over a year after the Italian collapse. In response, the British blockaded the port of Djibouti City but it could not prevent local French from providing information on the passing ship convoys. In 1942, about 4,000 British troops occupied the city. A local battalion from French Somaliland participated in the Liberation of Paris in 1944.
