Certain of the rebels fled to the United States, and there, in conjunction with American citizens, prepared to make incursions into Canada.

For this purpose they fitted out an American steamboat, the Caroline.

An expedition from Canada crossed the Niagara River to the American shore, set fire to the Caroline, and let her drift over the Falls.

In the fray which occurred, an American named Durfree was killed.

The British government avowed this invasion to be a public act and a necessary measure of self-defence; but it was a question when Mr.Van Buren went out of office whether this avowal had been made in an authentic manner.
