Britain and Austria organize a new coalition against France in 1798, including for the first time Russia, although no action occurs until 1799 except against Naples.
Another expeditionary force is sent to County Mayo to assist in the rebellion against Britain in the summer of 1798.
It has some success against British forces, most notably at Castlebar, but is ultimately routed while trying to reach Dublin.
French ships sent to assist them are captured by the Royal Navy off County Donegal.
