in Cadiz. The Peninsular war proved a major disaster for France. Napoleon did well when he was in direct charge, but severe losses followed his departure, as he severely underestimated how much manpower would be needed. The effort in Spain was a drain on money, manpower and prestige. Historian David Gates called it the "Spanish ulcer." Napoleon realised it had been a disaster for his cause, writing later, "That unfortunate war destroyed me ... All the circumstances of my disasters are bound up in that fatal knot." The Peninsular campaigns witnessed 60 major battles and 30 major sieges, more than any other of the Napoleonic conflicts, and lasted over six years, far longer than any of the others. France and her allies lost at least 91,000 killed in action and 237,000 wounded in the peninsula. From 1812, the Peninsular War merged with the War of the Sixth Coalition. War of the Fifth Coalition, 1809 The Fifth Coalition (1809) of Britain and Austria against France formed as Britain engaged in the Peninsular War in Spain and Portugal. The sea became a major theatre of war against Napoleon's allies. Austria, previously an ally of France, took the opportunity to attempt to restore its imperial territories in Germany as held prior to Austerlitz. During the time of the Fifth Coalition, the Royal Navy won a succession of victories in the French colonies. On land the major battles included Battle of Raszyn, Battle of Eckmuhl, Battle of Raab, Battle of Aspern-Essling, and Battle of Wagram. On land, the Fifth Coalition attempted few extensive military endeavours. One, the Walcheren Expedition of 1809, involved a dual effort by the British Army and the Royal Navy to relieve Austrian forces under intense French pressure. It ended in disaster after the Army commander, John Pitt, 2nd Earl of Chatham, failed to capture the objective, the naval base of French-controlled Antwerp. For the most part of the years of the Fifth Coalition, British military operations on land (apart from the Iberian Peninsula) remained restricted to hit-and-run operations executed by the Royal Navy, which dominated the sea after having beaten down almost all substantial naval opposition from France and its allies and blockading what remained of France's naval forces in heavily fortified French-controlled ports. These rapid-attack operations were aimed mostly at destroying blockaded French naval and mercantile shipping and the disruption of French supplies, communications, and military units stationed near
