On June 15th Napoleon's army crossed the Sambre, and on the morning of the 16th at Ligny he forced back the Prussians, but Blucher--falling back upon Wavre instead of Ligny--upset the French General's calculations. Meanwhile Wellington, having made arrangements with Blucher, was with his officers in the celebrated ballroom of the Duchess of Richmond at Brussels. Two hours after midnight the gaiety of the brilliant ballroom was subdued, and following the "sound of revelry by night" came "the cannon's opening roar" at Quatre Bras.
=Quatre Bras.=--By 8 o'clock the British had left Brussels, the 42nd and 92nd Highland Regiments having assembled to the sound of the pibroch, "Come to me and I will give you flesh"--an invitation to the wolf and raven, for which, as Forbes relates, the coming day did in fact spread an ample banquet. At 2 o'clock, after a march of 20 miles in sultry weather, they arrived at the hamlet of Quatre Bras, to find the Prince of Orange pluckily but feebly endeavouring to check the enemy, who had already gained Le Bois de Bossu. There, at the intersection of the Charleroi-Brussels and Namur-Nivelle roads, 7,000 Dutch-Belgians with 16 guns and no cavalry stood against Marshal Ney with 16,000 infantry, 1,700 cavalry, and 36 guns. It was, indeed, an unequal contest until the arrival of Pack's and Kempt's brigades. Wellington at once decided the wood must be taken, and then ensued an exceedingly sanguinary conflict ere, with the ultimate arrival of the Guards, the French were forced to retire. The Guards (mostly young soldiers) had arrived from Enghein after a march of 27 miles, having started at 3 o'clock in the morning to join the main body. They had halted at Nivelles to rest and feed, but the arrival of a Staff officer, urging them to hurry on, induced them to abandon their meal, and resume their march. They arrived on the field of battle at an opportune moment, and then, despite their fifteen hours' march without food or drink, the first brigade of Guards, having loaded their muskets and fixed bayonets, pushed their way into Le Bois de Bossu, and within half an hour regained possession of it, but they could do no more than hold it. Meanwhile a series of splendid struggles had been taking place. When the 95th had been ordered to clear Le Bois de Bossu, the Royals and the 28th (Gloucesters) were severely engaged on the left, while the 44th, the 42nd and 92nd Highland Regiments were hotly assailed on the right.
