Some Anguillan History
St. Kitts has two political parties and two newspapers. The Labour party, which is the one in power, has the Labour Spokesman. The People's Action Movement (PAM) has the Democrat. Both of them are embarrassing. But since a new editor took over in 2004 it has improved considerably.
Anyway they recently ran an article that is as much of the history of Anguilla as you are likely to find anywhere.
In 1967 Anguilla seceded from the union of St. Kitts, Nevis and Anguilla. A small force of Anguillans also tried to invade St. Kitts. To grasp this thing you must understand that Anguilla at the time had a population of less than 2,000 people and was 70 miles away on the far side of St. Maarten/St. Martin.
This article tells the Anguilla side of it.
