Walcheren Campaign

The blockade of the Scheldt was declared as early as 14 May 1809, but no reconnaissance or sounding of the entrance fairways has been carried out before the campaign began.^[1]

In July 1809, the British decided to seal the estuary of the Scheldt to prevent the port of Antwerp being used as a base against them.^[7] The primary aim of the campaign was to destroy the French fleet thought to be in Flushing while providing a diversion for the hard-pressed Austrians. However, the Battle 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, and Sir Richard Strachan commanded the navy, the full expeditionary force of 37 ships, the greatest to have ever left England, leaving The Downs on 28 July. Commanders included Hugh Downman, Edward Codrington, Amelius Beauclerk, William Charles Fahie, George Cockburn and George Dundas.^[8]

As a first move, the British seized the swampy island of Walcheren at the mouth of river Scheldt, as well as South Beveland island, both in the present-day Netherlands. The British troops soon began to suffer from "Walcheren fever", due to the symptoms present most likely a combination of malaria, typhus, typhoid and dysentery.^[9] 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-general Eyre Coote who in October was replaced by Lieutenant-general George Don.^[7]

The British were divided into three columns: "Walcheren" (whose task was to capture Walcheren Island and the fortifications of Flushing), "Schouwen", and "Cadzand". On 31 July the Walcheren Column seized the Veere fortification and moved to Flushing. On 1 August, the Schouwen Column landed at Wemeldinge, taking the Bath fortification (which blocked the entrances to both branches of the Scheldt) without a fight the next day, while a misunderstanding led the Cadzand Column to land on South Beveland on 31 July, allowing the French to reinforce Flushing via a pontoon bridge between Walcheren and Cadzand until 8 August. It is incomprehensible why Lord Chatham, having an entire squadron, was unable to break this connection in time. With the capture of Bath, the British opened the road to Antwerp through the eastern arm of the Scheldt, accessible to small frigates and gunboats, and to South Beveland. Despite a 40,000-man corps, Lord Chatham's decision to besiege Flushing for two weeks rather than advancing directly to Antwerp left a 21,000-man force idle at Bath, stalling the expedition.^[1]

On 30 July, the French garrisons in the Low Countries were distributed as follows:

• Flushing – 4,000;
• Cadzand – 300;
• Antwerp – 2,400;
• St. Omer – 6,000;
• Ghent – 3,000–4,000;
• the rest of the Low Countries – 3,000.^[1]

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 spanning French-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 Marshal Jean-Baptiste Bernadotte, the Prince of Ponte Corvo, who had recently resigned his command after incurring Napoleon's displeasure at the Battle of Wagram as overall commander of the invasion zone.^[10] 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.^[11] Bernadotte led the reinforced and reorganized French forces competently and although the British had captured Flushing 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 to Antwerp and heavily reinforced the city. By this time the French had already managed to concentrate up to 40,000 men in Antwerp and put the main forts of the Upper Scheldt into a defensive state. A rapid and decisive forward movement might still have saved the expedition, but instead, Lord Chatham confined himself to aimless skirmishing with the forts of the Upper Scheldt, bombarded Cadzand and Fort Terneuzen, and finally, on 26 August, convened a council of war. At this council, it became clear that an advance on Antwerp was utterly impossible, as the French (under Bernadotte) had already managed to concentrate nearly 100,000 men there. Both the French numbers and defences were such that the main objective for the British, Antwerp, was now out of reach. The British began a staged withdrawal to Walcheren.^[1]

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]} The French had no great opportunity to eliminate Chatham's army, since the waterbodies were defended by the dominant British navy; and it is also worth noting that Bernadotte was generally a cautious army commander, as his subsequent actions in the German campaign of 1813 showed. It was precisely in the first half of September that Bernadotte was replaced by Marshal Jean-Baptiste Bessières, the Duke of Istria. Earlier, at Auerstedt in 1806, Bernadotte had let Napoleon down by omitting this battle, allowing the Prussians to inflict greater losses on Davout's French and the opportunity to escape. Bernadotte missed Eylau in 1807; he also launched two unsuccessful attacks at Wagram in 1809, and there would have been no need for the second one at all if not for his actions.^[12] Napoleon's distrust of Bernadotte even led him to dispatch General Reille to keep a keen eye on him in Antwerp. When Bernadotte stated in his news bulletin that "his 15,000 men would be enough to repel any British number," Napoleon said:

"This is the first occasion on which a General has been known to betray his position by an excess of vanity." (The implication here is that Bernadotte ostensibly revealed his numbers because they could easily fall into enemy hands.)^[13]

On 24 December, the remnants of Chatham's army, encircled by superior French forces, having destroyed the port facilities of Flushing, boarded ships.^[1]

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 join Wellington's army caused a permanent doubling of the sick lists there.^{[citation needed]}

This campaign led to the plant known as Thanet cress being introduced to Britain in the sick men's bedding.^[14]

The debacle was also a source of acute political embarrassment, in particular for Lord Castlereagh upon whom the former United Irishman, Peter Finnerty, who at the invitation of Sir Home Popham^[15] accompanied the expedition as a special correspondent for The Morning Chronicle, heaped the blame.^[16][17]

The below order of battle is for 28 July.

A fleet of around 40 vessels, including sixteen 74 gun warships of the third rate, participated under the overall command of Strachan. A number of smaller vessels including customs-house and excise cutters were also involved, as was a packet ship. The City of London, Loyal Greenwich, and Royal Harbour River Fencibles also contributed men to the expedition.^[24]

The 1st battalion of the Irish 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 to Napoleon and he together with Captain O'Reilly received the Légion d'honneur in gratitude.^[25]
