While the Union was being pushed slowly forward, the struggle abroad was passing through strange vicissitudes. At the opening of 1799 the efforts of the new coalition were crowned with success in every quarter. Though Naples had been turned into a Parthenopean Republic at the close of the previous year, and the French supremacy extended over the whole peninsula, the descent of an Austrian army from the Tyrol at the end of March, and a victory of the Russian and Austrian forces at Cassano, compelled the French army to evacuate Southern Italy and Lombardy, while a fresh defeat at Novi flung it back on the Maritime Alps. A campaign conducted with more varying success drove the armies which advanced into Germany back over the Rhine. In Switzerland however the stubborn energy of Massena enabled his soldiers to hold their ground against the combined attack of Russian and Austrian forces; and the attempt of a united force of Russians and English to wrest Holland from its French masters was successfully repulsed. Twelve of the thirty thousand men who formed this army consisted of English troops; and Sir Ralph Abercromby succeeded in landing at their head, in seizing what remained of the Dutch fleet at the Texel, and in holding General Brune at bay when he advanced with superior forces. But Abercromby was superseded in his command by the Duke of York; and in another month the new leader was glad to conclude a convention by which the safe withdrawal of his troops was secured.
