This is done in exchange for a discount of millions of dollars on Polaris nuclear submarines - a way of concealing the payment. The US pays rent of one dollar per year.

Christian Simon, in despair, commits suicide on the boat trip. [2]

The confused and frightened exiles have to find what accommodation they can. Most of them end up in slums, some in windowless animal huts. The last shipload of islanders stage a sit-down strike on board the ship and are rewarded with small payments of money from the High Commission, which deepens resentment among earlier exiles. [2] [10]

Housing estate houses and dockers flats are made available to some families because of demonstration onboard of Nordvaer. [2]

The British government transferes 650,000 to the Mauritian government for the aid of the Chagossian exiles. Some of this money is intended to be used to resettle the exiles on farm land but there is much disagreement and the exiles are so desperate for money, that the resettlement plan is abandoned and, eventually, in 1978 the money was disbursed. Although this money helps some of the exiles to obtain better housing, most of them are left no better off. All of them have been forced to borrow money in order to survive and their share has to be used to discharge their debts. [9] [10]


The British High Commission on Mauritius refuses to act on a petition presented by the islanders indicating their wish to return home. The British state that the "High Commission cannot intervene between yourselves as Mauritians and the government of Mauritius, who assumed responsibility for your resettlement".

This blow is followed a few days later by the refusal of permission to appeal a High Court ruling from October 2003 which denied the Chagossians compensation. [10]
