TheWalcheren Campaign (Dutch pronunciation:[ˈʋɑlxərə(n)]) was an unsuccessfulBritish expedition to theKingdom of Holland in 1809 intended to open another front in theAustrian Empire's struggle withFrance during theWar of the Fifth Coalition.John Pitt, 2nd Earl of Chatham, the commander of the expedition, was ordered to capture the towns ofFlushing andAntwerp and thus enable British ships to safely traverse theScheldt River.

A British expeditionary force of 39,000 troops, together with field artillery and two siege trains, crossed theNorth Sea and landed atWalcheren on 30 July. This was the largest British expedition of that year, larger than the army serving in thePeninsular War in theIberian Peninsula. Nevertheless, it failed to achieve any of its goals. The campaign involved little fighting, but heavy losses from the sickness popularly dubbed"Walcheren Fever". Although more than 4,000 British troops died during the expedition, only 106 werekilled in action; the survivors withdrew on 9 December. Defending Franco-Dutch forces also suffered heavy casualties, including 4,000 men dead, wounded or captured.^[1]

In July 1809, the British decided to seal theestuary of theScheldt to prevent theport of Antwerp being used as a base against them.^[2] The primary aim of the campaign was to destroy theFrench fleet thought to be inFlushing while providing a diversion for the hard-pressed Austrians. However, theBattle of Wagram had already occurred before the start of the campaign and the Austrians had effectively already lost the war.

John Pitt, 2nd Earl of Chatham commanded the army, andSir Richard Strachan commanded the navy, the full expeditionary force of 37 ships, the greatest to have ever left England, leavingThe Downs on 28 July. Commanders includedHugh Downman,Edward Codrington,Amelius Beauclerk,William Charles Fahie,George Cockburn andGeorge Dundas.^[3]

As a first move, the British seized the swampy island ofWalcheren at the mouth of riverScheldt, as well asSouth Beveland island, both in the present-dayNetherlands. The British troops soon began to suffer from "Walcheren fever", due to the symptoms present most likely a combination ofmalaria,typhus,typhoid anddysentery.^[4] Within a month of seizing the island, they had over 8,000 fever cases. The medical provisions for the expedition proved inadequate despite reports that an occupying French force had lost 80% of its numbers a few years earlier, also due to disease. Once it had been decided to garrison Walcheren Island in September 1809, Pitt was replaced by Lieutenant-generalEyre Coote who in October was replaced by Lieutenant-generalGeorge Don.^[2]

At the time of the initial landings, the French forces were characterized by a divided command over a motley crew of units manned by soldiers of many nationalities spanningFrench-occupied Europe. There were a few French units among those present considered to be of inferior quality as they were manned by the physically infirm and dregs of the training depots.^{[citation needed]}

However, on 10 August 1809, as reinforcements began flowing into the invasion zone, Napoleon approved the appointment of MarshalJean-Baptiste Bernadotte, the Prince ofPonte Corvo, who had recently resigned his command after incurring Napoleon's displeasure at theBattle of Wagram as overall commander of the invasion zone.^[5] Bernadotte had returned to Paris and was sent to defend the Netherlands by the council of ministers. His arrival gave the French a much-needed unity of command and he brought with him a genius for organization and training.^[6] Bernadotte led the reinforced and reorganized French forces competently and although the British had capturedFlushing on the day of his arrival to the war zone after a ferocious bombardment, and the surrounding towns on 15 August, he had already ordered the French fleet toAntwerp and heavily reinforced the city. The French numbers were such that the main objective for the British, Antwerp, was now out of reach. The expedition was called off in early September. Around 12,000 troops stayed on Walcheren, but by October only 5,500 remained fit for duty.^{[citation needed]}

In all, the British government spent almost £8 million on the campaign. Along with the 4,000 men who had died during the campaign, almost 12,000 were still ill by February 1810 and many others remained permanently weakened. Those sent to the Peninsular War to joinWellington's army caused a permanent doubling of the sick lists there.^{[citation needed]}

This campaign led to the plant known asThanet cress being introduced to Britain in the sick men's bedding.^[7]

The debacle was also a source of acute political embarrassment, in particular forLord Castlereagh upon whom the formerUnited Irishman,Peter Finnerty, who at the invitation ofSir Home Popham^[8] accompanied the expedition as a special correspondent forThe Morning Chronicle, heaped the blame.^[9][10]

The below order of battle is for 28 July.

A fleet of around 40 vessels, including sixteen74 gun warships of thethird rate, participated under the overall command of Strachan. A number of smaller vessels including customs-house and excise cutters were also involved, as was apacket ship. The City of London, Loyal Greenwich, and Royal HarbourRiver Fencibles also contributed men to the expedition.^[17]

The 1st battalion of theIrish Legion (raised by the French for an invasion of Ireland that never happened) was stationed in Flushing during the assault and received its baptism of fire there. It fought a rear guard action for several days but the battalion was almost completely captured. The Legion's brass band followed by the Irish battalion led the surrendered French garrison out of the town. However, a small party of Irishmen escaped and went into hiding with the battalion's cherished imperial eagle, and after a few days they crossed the Scheldt River and escaped. Commandant Lawless was presented toNapoleon and he together with Captain O'Reilly received the Légion d'honneur in gratitude.^[18]
