The troops could now obtain a view of the ground upon which they were to fight. Their line extended some two miles in length, along the brow of a gradually sloping rise, the two extremities of which projected somewhat beyond the center. The ground was open, without woods or hedgerows. About halfway down the slope lay four farms. On the right was Hougoumont; a chateau with farm buildings attached to it and a chapel. In front of this lay a thick wood with a close hedge, and the house and farm buildings were surrounded by a strong wall. In front of the center of the line lay the farm and inclosures of La Haye Sainte, abutting on the main Charleroi road, which, as it passed the farm, ran between two deep banks. In front of the left of the line were the hamlets of Papelotte and La Haye. At the top of the ridge the ground sloped backward, and the infantry were posted a little in rear of the crest, which hid them from the sight of the enemy, and protected them from artillery fire. The whole of the slope, and the valley beyond it was covered with waving corn or high grass, now ready for cutting.
Upon the opposite side of the valley there was a similar rise, and on this was the French position. Nearly in the center of this stood the farm called La Belle Alliance, close to which Napoleon took up his stand during the battle. Behind the British position the ground fell away and then rose again gently to a crest, on which stood the villages of Waterloo and Mount St. Jean. The great forest of Soignies extended to this point, so that if obliged to fall back Wellington had in his rear a position as defensible as that which he now occupied.
The allies were arranged in the following order: On the extreme left were Vandeleur's and Vivian's light cavalry brigades. Then came Picton's division, the first line being composed of Hanoverians, Dutch, and Belgians, with Pack's British brigade, which had suffered so severely in Quatre Bras, in its rear, and Kempt's brigade extending to the Charleroi road. Alten's division was on the right of Picton's. Its second brigade, close to the road, consisted of the First and Second light battalions of the German legion, and the Sixth and Eighth battalions of the line. The Second German battalion was stationed in the farm of La Haye Sainte. Next to these came a Hanoverian brigade, on the right of whom were Halket's British brigade. On the extreme right was Cooke's division, consisting of two brigades of the guards, having with them a Nassau regiment, and two companies of Hanoverian riflemen.
Behind the infantry line lay the cavalry. In reserve were a brigade of the fourth division, the whole of the second division, and the Brunswickers, Dutch, and Belgians. The artillery were placed at intervals between the infantry, and on various commanding points along the ridge.
The duke had expected to be attacked early, as it was of the utmost importance to Napoleon to crush the British before the Prussians could come up; but the rain, which began to hold up as daylight appeared, had so soddened the deep soil that Napoleon thought that his cavalry, upon whom he greatly depended, would not be able to act, and he therefore lost many precious hours before he set his troops in motion.
From the British position the heavy masses of French troops could be seen moving on the opposite heights to get into the position assigned to them; for it was scarcely a mile from the crest of one slope to that of the other.
In point of numbers the armies were not ill-matched. Wellington had forty-nine thousand six hundred and eight infantry twelve thousand four hundred and two cavalry, five thousand six hundred and forty-five artillerymen, and one hundred and fifty-six guns. Napoleon, who had detached Grouchy with his division in pursuit of the Prussians, had with him forty-eight thousand nine hundred and fifty infantry, fifteen thousand seven hundred and sixty-five cavalry, seven thousand two hundred and thirty-two artillerymen, and two hundred and forty-six guns. He had, therefore, four thousand three hundred men and ninety guns more than Wellington. But this does not represent the full disparity of strength, for Wellington had but eighteen thousand five hundred British infantry including the German legion—who having fought through the Peninsular were excellent troops—seven thousand eight hundred cavalry and three thousand five hundred artillery. The remainder of his force consisted of troops of Hanover, Brunswick, Nassau, Holland, and Belgium, upon whom comparatively little reliance could be placed. The British infantry consisted almost entirely of young soldiers; while the whole of Napoleon's force were veterans.
As early as six o'clock in the morning both armies had taken up the positions in which they were intended to fight. The British infantry were lying down, the cavalry dismounted in their rear, and so completely were they hidden from the sight of the French that Napoleon believed they had retreated, and was greatly enraged at their having, as he supposed, escaped him. While he was expressing his annoyance, General Foy, who had served against the duke in the Peninsula, rode up and said:
"Your majesty is distressing yourself without just reason, Wellington never shows his troops until they are needed. A patrol of horse will soon find out whether he is before us or not, and if he be I warn your majesty that the British infantry are the very devil to fight."
The emperor soon discovered that the British were still in front of him; for the English regiments were directed to clean their arms by firing them off, and the heavy fusillade reached Napoleon's ears. At eight o'clock Wellington, who was anxiously looking over in the direction from which he expected the Prussians to appear, saw a body of mounted men in the distance, and soon afterward a Prussian orderly rode in and informed him that they were on the march to his assistance, and would soon be on the field.
