The overthrow of Austria and Prussia by Napoleon in 1805 and 1806, followed in 1807 by the Peace of Tilsit with Russia, made the emperor once more turn his attention to the project of an invasion of his hated enemy, England. A great French fleet was to be concentrated on the Scheldt, with Antwerp and Flushing for its bases. For this purpose large sums of money were expended in converting Antwerp into a formidable naval arsenal. But the British government were well aware of “the pistol that was being aimed at England’s breast”; and in 1809 a powerful expedition under the command of Lord Chatham was despatched, consisting of more than 100 warships and transports, with the object of destroying these growing dockyards and arsenals, and with them the threat of invasion. The attack was planned at a favourable moment, for the defensive force was very small, the bulk of the Dutch army having been sent to fight in the Austrian and Spanish campaigns, and the French garrisons greatly reduced. Chatham landed on the island of Walcheren, captured Middelburg and Veere and on August 15 compelled Flushing to surrender after such a furious bombardment that scarcely any houses remained standing. The islands of Schouwen, Duiveland and Zuid-Beveland were overrun; and, had the British general pushed on without delay, Antwerp might have fallen. But this he failed to do; and meanwhile Louis had collected, for the defence of the town, a force of 20,000 men, which, to his deep chagrin, Napoleon did not allow him to command. No attack however was made on Antwerp by the British, who had suffered severely from the fevers of Walcheren; and on the news of Wagram and the Treaty of Schoenbrunn they slowly evacuated their conquests. Before the end of the year the whole force had returned to England.
This invasion, though successfully repelled, only accentuated the dissensions between the two brothers. French troops remained in occupation of Zeeland; and the French army of the north at Antwerp, now placed under the command of Marshal Oudinot, lay ready to enforce the demands of the emperor should the Dutch government prove recalcitrant. Those demands included the absolute suppression of smuggling, the strictest enforcement of the decrees against trading with England, conscription, and a repudiation of a portion of the State debt. Napoleon overwhelmed his brother with bitter gibes and angry threats, declaring that he wished to make Holland an English colony, and
