WATERLOO, June 19, 1815[1]

My Lord,

Bonaparte, having collected the 1st, 2nd, 3rd, 4th, and 6th corps of the French army, and the Imperial Guards, and nearly all the cavalry, on the Sambre, and between that river and the Meuse, between the 10th and 14th of the month, advanced on the 15th and attacked the Prussian posts at Thuin and Lobbes, on the Sambre, at daylight in the morning.

I did not hear of these events till in the evening of the 15th; and I immediately ordered the troops to prepare to march, and afterwards to march to their left, as soon as I had intelligence from other quarters to prove that the enemy's movement upon Charleroi was the real attack.

The enemy drove the Prussian posts from the Sambre on that day; and General Ziethen, who commanded the corps which had been at Charleroi, retired upon Fleurus; and Marshal Prince Blücher concentrated the Prussian army upon Sombreffe, holding the villages in front of his position of St. Amand and Ligny.

The enemy continued his march along the road from Charleroi towards Brussels; and on the same evening, the 15th, attacked a brigade of the army of the Netherlands, under the Prince de Weimar, posted at Frasne, and forced it back to the farmhouse, on the same road, called Les Quatre Bras.

The Prince of Orange immediately reinforced this brigade with another of the same division, under General Perponcher, and, in the morning early, regained part of the ground which had been lost, so as to have the command of the communication leading from Nivelles and Brussels with Marshal Blücher's position.

In the meantime I had directed the whole army to march upon Les Quatre Bras; and the 5th Division, under Lieutenant-General Sir Thomas Picton, arrived at about half-past two in the day, followed by the corps of troops under the Duke of Brunswick, and afterwards by the contingent of Nassau.

At this time the enemy commenced an attack upon Prince Blücher with his whole force, excepting the 1st and 2nd Corps, and a corps of cavalry under General Kellermann, with which he attacked our post at Les Quatre Bras.

The Prussian army maintained their position with their usual gallantry and perseverance against a great disparity of numbers, as the 4th Corps of their army, under General Bülow, had not joined; and I was attacked myself, and the troops, the cavalry in particular, which had a long distance to march, had not arrived.

We maintained our position also, and completely defeated and repulsed all the enemy's attempts to get possession of it. The enemy repeatedly attacked us with a large body of infantry and cavalry, supported by a numerous and powerful artillery. He made several charges with the cavalry upon our infantry, but all were repulsed in the steadiest manner.

In this affair His Royal Highness the Prince of Orange, the Duke of Brunswick, and Lieutenant-General Sir Thomas Picton, and Major-Generals Sir James Kempt and Sir Denis Pack, who were engaged from the commencement of the enemy's attack, highly distinguished themselves, as well as Lieutenant-General Charles Baron Alten, Major-General Sir C. Halkett, Lieutenant-General Cooke, and Major-Generals Maitland and Byng, as they successively arrived. The troops of the 5th Division, and those of the Brunswick corps, were long and severely engaged, and conducted themselves with the utmost gallantry. I must particularly mention the 28th, 42nd, 79th, and 92nd Regiments, and the battalion of Hanoverians.

Our loss was great, as your lordship will perceive by the enclosed return, and I have particularly to regret His Serene Highness the Duke of Brunswick, who fell fighting gallantly at the head of his troops.

Although Marshal Blücher had maintained his position at Sombreffe, he still found himself much weakened by the severity of the contest in which he had been engaged, and, as the 4th Corps had not arrived, he determined to fall back, and to concentrate his army upon Wavre; and he marched in the night, after the action was over.

This movement of the Marshal rendered necessary a corresponding one upon my part; and I retired from the farm of Quatre Bras upon Genappe, and thence upon Waterloo the next morning, the 17th, at ten o'clock.

The enemy made no effort to pursue Marshal Blücher. On the contrary, a patrol which I sent to Sombreffe in the morning found all quiet, and the enemy's vedettes fell back as the patrol advanced. Neither did he attempt to molest our march to the rear, although made in the middle of the day, excepting by following, with a large body of cavalry brought from his right, the cavalry under the Earl of Uxbridge.

This gave Lord Uxbridge an opportunity of charging them with the 1st Life Guards, upon their débouché from the village of Genappe, upon which occasion his lordship has declared himself to be well satisfied with that regiment.

The position which I took up in front of Waterloo crossed the highroads from Charleroi and Nivelles, and had its right thrown back to a ravine near Merke Braine, which was occupied, and its left extended to a height above the hamlet Ter la Haye, which was likewise occupied. In front of the right center, and near the Nivelles road, we occupied the house and gardens of Hougoumont, which covered the return of that flank; and in front of the left center we occupied the farm of La Haye Sainte. By our left we communicated with Marshal Prince Blücher at Wavre, through Ohain; and the Marshal had promised me that, in case we should be attacked, he would support me with one or more corps, as might be necessary.

The enemy collected his army, with the exception of the 3rd Corps, which had been sent to observe Marshal Blücher, on a range of heights in our front, in the course of the night of the 17th and yesterday morning, and at about ten o'clock he commenced a furious attack upon our post at Hougoumont. I had occupied that post with a detachment from General Byng's brigade of Guards, which was in position in its rear; and it was for some time under the command of Lieutenant-Colonel Macdonell, and afterwards of Colonel Home; and I am happy to add that it was maintained throughout the day with the utmost gallantry by these brave troops, notwithstanding the repeated efforts of large bodies of the enemy to obtain possession of it.

This attack upon the right of our center was accompanied by a very heavy cannonade upon our whole line, which was destined to support the repeated attacks of cavalry and infantry, occasionally mixed, but sometimes separate, which were made upon it. In one of these the enemy carried the farmhouse of La Haye Sainte, as the detachment of the light battalion of the German Legion, which occupied it, had expended all its ammunition; and the enemy occupied the only communication there was with them.

The enemy repeatedly charged our infantry with his cavalry, but these attacks were uniformly unsuccessful; and they afforded opportunities to our cavalry to charge, in one of which Lord E. Somerset's brigade, consisting of the Life Guards, the Royal Horse Guards, and 1st Dragoon Guards, highly distinguished themselves, as did that of Major-General Sir William Ponsonby, having taken many prisoners and an eagle.

These attacks were repeated till about seven in the evening, when the enemy made a desperate effort with cavalry and infantry, supported by the fire of artillery, to force our left center, near the farm of La Haye Sainte, which after a severe contest was defeated; and, having observed that the troops retired from this attack in great confusion, and that the march of General Bülow's corps, by Frischermont upon Planchenois and La Belle Alliance, had begun to take effect, and as I could perceive the fire of his cannon, and as Marshal Prince Blücher had joined in person with a corps of his army to the left of our line by Ohain, I determined to attack the enemy, and immediately advanced the whole line of infantry, supported by the cavalry and artillery. The attack succeeded in every point: the enemy was forced from his positions on the heights, and fled in the utmost confusion, leaving behind him, as far as I could judge, 150 pieces of cannon, with their ammunition, which fell into our hands.

I continued the pursuit till long after dark, and then discontinued it only on account of the fatigue of our troops, who had been engaged during twelve hours, and because I found myself on the same road with Marshal Blücher, who assured me of his intention to follow the enemy throughout the night. He has sent me word this morning that he had taken 60 pieces of cannon belonging to the Imperial Guard, and several carriages, baggage, etc., belonging to Bonaparte in Genappe.

I propose to move this morning upon Nivelles, and not to discontinue my operations.

Your lordship will observe that such a desperate action could not be fought, and such advantages could not be gained, without great loss; and I am sorry to add that ours has been immense. In Lieutenant-General Sir Thomas Picton His Majesty has sustained the loss of an officer who has frequently distinguished himself in his service, and he fell gloriously leading his division to a charge with bayonets, by which one of the most serious attacks made by the enemy on our position was repulsed. The Earl of Uxbridge, after having successfully got through this arduous day, received a wound by almost the last shot fired, which will, I am afraid, deprive His Majesty for some time of his services.

His Royal Highness the Prince of Orange distinguished himself by his gallantry and conduct, till he received a wound from a musket-ball through the shoulder, which obliged him to quit the field.

It gives me the greatest satisfaction to assure your lordship that the army never upon any occasion conducted itself better. The division of Guards, under Lieutenant-General Cooke, who is severely wounded, Major-General Maitland, and Major-General Byng, set an example which was followed by all, and there is no officer nor description of troops that did not behave well.

I must, however, particularly mention for His Royal Highness's approbation Lieutenant-General Sir H. Clinton, Major-General Adam, Lieutenant-General Charles Baron Alten (severely wounded), Major-General Sir Colin Halkett (severely wounded), Colonel Ompteda, Colonel Mitchell (commanding a brigade of the 4th Division), Major-Generals Sir James Kempt and Sir D. Pack, Major-General Lambert, Major-General Lord E. Somerset, Major-General Sir W. Ponsonby, Major-General Sir C. Grant, and Major-General Sir H. Vivian, Major-General Sir O. Vandeleur, and Major-General Count Dornberg.

I am also particularly indebted to General Lord Hill for his assistance and conduct upon this, as upon all former occasions.

The artillery and engineer departments were conducted much to my satisfaction by Colonel Sir George Wood and Colonel Smyth; and I had every reason to be satisfied with the conduct of the Adjutant-General, Major-General Barnes, who was wounded, and of the Quartermaster-General, Colonel De Lancey, who was killed by a cannon-shot in the middle of the action. This officer is a serious loss to His Majesty's service, and to me at this moment.

I was likewise much indebted to the assistance of Lieutenant-Colonel Lord FitzRoy Somerset, who was severely wounded, and of the officers composing my personal staff, who have suffered severely in this action. Lieutenant-Colonel the Hon. Sir Alexander Gordon, who has died of his wounds, was a most promising officer, and is a serious loss to His Majesty's service.

General Kruse, of the Nassau service, likewise conducted himself much to my satisfaction, as did General Tripp, commanding the heavy brigade of cavalry, and General Vanhope, commanding a brigade of infantry, in the service of the King of the Netherlands.

General Pozzo di Borgo, General Baron Vincent, General Müffling, and General Alava, were in the field during the action, and rendered me every assistance in their power. Baron Vincent is wounded, but I hope not severely, and General Pozzo di Borgo received a contusion.

I should not do justice to my own feelings, or to Marshal Blücher and the Prussian Army, if I did not attribute the successful result of this arduous day to the cordial and timely assistance I received from them. The operation of General Bülow upon the enemy's flank was a most decisive one; and even if I had not found myself in a situation to make the attack which produced the final result, it would have forced the enemy to retire if his attacks should have failed, and would have prevented him from taking advantage of them if they should unfortunately have succeeded.

Since writing the above, I have received a report that Major-General Sir William Ponsonby is killed, and, in announcing this intelligence to your lordship, I have to add the expression of my grief for the fate of an officer who had already rendered very brilliant and important services, and was an ornament to his profession.

I send with this dispatch three eagles, taken by the troops in this action, which Major Percy will have the honor of laying at the feet of His Royal Highness. I beg leave to recommend him to your lordship's protection.



I have the honor to be, etc.,
