This army was organized, as we have said above, into two corps and a reserve, in addition to which was a large body of cavalry, and a small force of reserve artillery. There were six (so-called) British divisions in the army, only one of which, the 1st, Cooke’s, was composed entirely of British troops,—the Guards; the others contained troops of the King’s German Legion and Hanoverians. To each of these divisions were attached two batteries. Six troops of horse-artillery were attached to the cavalry.

The 1st and 3d British divisions, those of Cooke and Alten, with the 2d and 3d Dutch-Belgian divisions of Perponcher and Chassé, composed the 1st Corps under the Prince of Orange. They covered the front of the army from Quatre Bras to and beyond Enghien, occupying the country in and around Nivelles, Roeulx, Soignies and Braine-le-Comte. They numbered 25,233 men, with 48 guns.

The 2d and 4th British divisions, those of Clinton and Colville, with the 1st Dutch-Belgian division of Stedmann, and Anthing’s Indian brigade, constituted the 2d Corps under Lord Hill. They continued the line of the army to the north and west, occupying the country in and around Ath, Grammont and Audenarde. They numbered 24,033 men, with 40 guns.

The Reserve, or rather that portion of it destined for service in the field, and not counting the troops on garrison-duty, was under the immediate direction of the commander-in-chief. It was composed of the 5th and 6th British divisions, those of Picton and Cole, of the Brunswick Corps under the Duke of Brunswick, and of the Nassau contingent under General Kruse. They numbered 20,563 men, with 64 guns.

The British and King’s German Legion cavalry was composed of seven brigades, the whole under Lord Uxbridge. They numbered 8,473 men. To this corps were attached, as has been stated, six horse batteries. This cavalry was stationed mainly in rear of the 2d Corps, near Ninove and Grammont; but one brigade under General Dörnberg was at and in the neighborhood of Mons.

The Hanoverian, Brunswick and Dutch-Belgian cavalry were attached respectively to the various divisions of these troops. They numbered 6,009 men, with one horse-battery of 8 guns.

Of this miscellaneous force the Duke relied really only on his English troops and those of the King’s German Legion, a corps raised originally in Hanover, which had for many years belonged to the English crown. These troops had served in the Peninsula for several years with great credit. The Hanoverian contingent, strictly so called, was composed of very raw troops, and the same was true of the Dutch-Belgians. Little was known about the Brunswickers and Nassauers. The fidelity of many of the allied troops was strongly suspected, as they had been raised in countries which had for the past few years been subject to France, and the sympathies of the soldiers were supposed to be with Napoleon.[53] The Duke’s opinion of his army is well known. He considered it the poorest he had ever led.[54] Very possibly he may have underestimated its quality; but certain it is that the force which he commanded was a very heterogeneous collection of troops, that they had never acted in the field as an army before, and that the character and steadiness of a considerable number were, on account of either disaffection or inexperience, gravely doubted by their commander.

All this was in all probability known to Napoleon, and served as the basis of his expectations, as we shall see later on.
