To the Editor:

Not mentioned in Andro Linklater's explanation of the Louisiana Purchase as a real estate deal (''565 Million Acres, Riv Vu,'' Op-Ed, April 28) is the crucial role played by the Haitian revolution.

Napoleon wanted an empire in the West, but first he had to suppress the slave revolt in Hispaniola, where Toussaint L'Ouverture had led the Haitians to victory. The French lost thousands of soldiers in trying to do so and returned to France defeated. That prevented the French from going to Louisiana. Without Haiti, one of France's richest colonies, Napoleon gave up on his dreams of a Western empire and made the deal to sell Louisiana.

This history is often overlooked. One hopes that will not occur with regard to next year's celebration of the 200th anniversary of the Haitian revolution.
