The Mystery of Lord Chatham’s Brigade at the Battle of Castricum, 6 October 1799. By Jacqueline Reiter.

Between the end of August and mid-October 1799, Britain and Russia fielded a combined force of about 45,000 men in North Holland as part of the Second Continental Coalition against France. The campaign’s intention was to take Amsterdam, push the French out of the Batavian Republic and re-establish the deposed House of Orange, preferably with the help of a popular uprising.

This did not occur, and poor weather delayed the Allied advance. Although a series of battles on 27 August, 19 September, and 2 and 6 October forced the French back, the Allies were low on supplies, riddled with sickness, and unable to rely on local support. They made terms on 18 October and were permitted to evacuate unmolested in exchange for releasing 8000 French prisoners of war from Britain.

The Helder campaign is of particular interest to me because my research subject, the 2nd Earl of Chatham, commanded the 7th Brigade in the British expeditionary force.
With a continental campaign in mind, the British army had been hastily bulked up in the spring of 1799 by a militia draft of 10,500 men. Chatham’s brigade of 4000 men was composed of two skeleton regiments that had been built up to full strength from this draft. The 4th Foot (or “King’s Own”) received over 2700 militia recruits and was divided into three battalions; the 31st, which had been decimated in the West Indies, received 955.[1]
This “militia brigade” was just as raw as its brigadier. Although Chatham had been in the army since 1774, he only had experience of garrison duty and had resigned his commission for personal reasons in 1785. He had, however, been allowed to retain his seniority (being the prime minister’s brother had its perks) and was now a Major-General.

Chatham’s brigade did not land in Holland until mid- September, and was not directly involved in any fighting until 2 October, when it played a significant role in advancing the British lines, for which Chatham was commended in the dispatches. Four days later, on 6 October, Chatham’s brigade again played a pivotal role.
Unlike the battle of 2 October, which was described at great length in the dispatches, no single coherent account of the 6 October battle exists. The Duke of York, Commander-in-Chief of the Allied forces, merely recorded in his official dispatch: “The enemy on their part advanced their whole force; the action became general along the whole line … and was maintained with great obstinacy on both sides until night, when the enemy retired, leaving us masters of the field of battle.”[2]
Several things explain this lack of information. For one thing, the battle was entirely unexpected. York had merely commanded his troops to advance to the villages of Ackersloot, Limmen and Bakkum, in preparation for a future assault on the French and Dutch positions at Beverwijk. The Russians tried to secure their position and over-extended themselves in the direction of Castricum, which turned out to be far better defended than anyone had anticipated.

This triggered a full-scale French retaliation, and General Abercromby’s division, stationed around the village of Egmont-op-Zee (now Egmond-aan-Zee), was called in to reinforce the Russians.
Adding to the confusion, the weather was terrible. “The rain poured down in torrents,” recorded one of York’s aides-de-camp. “… The country … was extremely intricate, and the thick rain and the heavy smoke dwelling on the copse-woods, and inclosures of the villages made it impossible to distinguish anything clearly.”[3] According to another source: “The morning loured … a deep mist prevented the view of either friend or enemy”.[4]

Broad, sandy dunes (described by Sir John Fortescue as “a tangle of little hills”)[5] divided the brigades from each other and made it difficult to see far ahead, even without the mist, smoke and rain. The Duke of York, who remained in Alkmaar the whole time, sent one of his aides up St Laurence’s Church tower with a telescope to see what was going on. This did not work, and headquarters were unaware that British troops were heavily engaged with the enemy for some hours.

Chatham’s brigade was one of the most heavily involved in the fighting. The statistics speak for themselves. The King’s Own lost 496 killed, wounded and captured, including three lieutenant-colonels. Of that number, 352 were captured when a portion of the 2nd and 3rd battalions got separated in the dunes, got confused in the rain and smoke and “forced their way within the Enemy Lines, without knowing at all where they were”.[6] The 31st lost 133. Altogether, Chatham’s brigade lost about 630 men at a conservative estimate – a sizeable proportion of the whole brigade, nearly half the 1400 British casualties, and a fifth of the 3200 total allied casualties.[7]

This did not even include one high-profile casualty, Lord Chatham, who received a spent musket-ball to the shoulder. Back home, prime minister Pitt hastened to assure Lady Chatham that her husband was “perfectly safe and well”, and the ball seems to have been “repell’d in a great degree by part of the Epaulet [sic]”.[8] Nevertheless, the incident came as a shock to many, including Chatham himself, who had his coat and waistcoat “forced away” and suffered “a great contusion on his shoulder”.[9]

The possibility that Chatham might have been seriously wounded probably kept the news out of the official gazettes; the prime minister was, after all, Chatham’s heir, and could ill afford to go to the House of Lords. (The secrecy doesn’t seem to have worked: a rumour got out that Chatham had been killed, and at least one worried stockholder sent a suggestion to Henry Dundas, Secretary of State for War, that a law should be introduced “to keep Mr Pitt in the House of Commons”.)[10]
What was Chatham doing on 6 October? Whatever it was, the result was devastation for his brigade. Sir John Fortescue tried and failed to discover where Chatham was engaged, although he felt it wasn’t really significant: “Under so incompetent a brigadier they were likely to come to misfortune in any position.”[11] This is rather unfair, particularly given Fortescue’s admission that he could not work out where Chatham was.

Three pieces of evidence, however, give a clue. The first is a letter from Chatham himself. On 4 October, Chatham wrote to his mother from Egmont-op-Zee, telling her that “I moved in the course of yesterday to this place to reinforce Sir Ralph Abercromby … we have marched in this morning”.[12]

The second is a letter from Colonel MacDonald, dated 7 October, recording that he had “had the honor of conversing with [Lord Chatham] about two hours ago at Egmont op Zee” – where Chatham had returned after the action of the 6th.[13] Clearly Chatham‘s Brigade formed part of the reinforcements sent by Abercromby to assist the Russians in the dunes surrounding Castricum.
The third clue about Chatham’s deployment is a letter from Christopher Hely-Hutchinson, brother of General John Hutchinson, whose brigade was also heavily damaged during the 6 October battle:
“The Russians, with Colonel McDonald’s Brigade, advanced rather too far upon the enemy, who came down upon them in great force. Our Brigade, with that of Lord Chatham’s, & General D’Oyly’s, advanc’d to their support. We advanced along the sand hills, with orders to support General D’Oyly who was on our left. … The enemy were in considerable force on our front”.[14]
From this account, it seems clear that Chatham was involved in the thickest fighting. According to the regimental history of the 4th Foot, the regiment “principally sustained the shock of the enemy’s horse”.[15] Most likely what happened was that Chatham’s brigade became caught up in the Russian’s retreat when they were beaten out of Castricum by one of the enemy cavalry charges. Given the restricted visibility and the presence of the routed Russians to the front, the brigade (unseasoned militiamen that they were) probably did not have time to form a square, or botched the manoeuvre and suffered accordingly.
Chatham left no account of his experience, perhaps partly because his wound left him temporarily unable to write (all accounts of his safety were conveyed to his family by third parties). One thing is certain: Castricum stopped him being sent abroad again during Pitt’s lifetime. Pitt’s 20th century biographers were flippant about the incident – P.W. Wilson, for example, joked that “Pitt’s career was safeguarded by the fraternal gold lace”,[16] but the reaction of Pitt’s friends to Chatham’s near-miss was one of frank horror. Chatham’s cousin Lord Buckingham wrote to Lord Grenville:
Lord Chatham’s escape has, I trust, decided you and others to whom the public have a right to look, not to suffer yourselves to forego for his very proper feelings as a soldier the dearest interests of the public; and that, in one word, his further service on the Continent will be negatived; a sacrifice which, I must say, he owes to the public.[17]
Nor was Buckingham alone in his assessment. Henry Dundas told Pitt that all would “concur … in reprobating the idea of Lord Chatham’s going at present upon any foreign Service, and the King will be under the necessity of interposing to prevent it”.[18]
It would be ten years before Chatham had the opportunity to serve abroad again, at which point Pitt had been dead for three years. The sphere of engagement was again Holland; the result was even more disastrous than the Helder campaign. But Walcheren is another story.
