Army and all the military Bureaux have received orders to repair and are now on their march to Antwerp, and the road thither is so covered and blocked up by waggons that the retreat of our Army will be much impeded thereby. Probably my next letter may be dated from a French prison. BRUXELLES, June 21. Judge, my friend, of my astonishment and that of almost everybody in this city, at the news which was circulated here early on the morning of the 19th, and has been daily confirmed, viz., that the French Army had been completely defeated and was in full flight, leaving behind it 220 pieces of cannon and all its baggage, waggons and _munitions de guerre_. I have not been able to collect all the particulars, but you will no doubt hear enough of it, for I am sure it will be _said_ or _sung_ by all the partisans of the British ministry and all the Tories of the United Kingdom for months and years to come; for further details, therefore, I shall refer you to the Gazette. The following, however, you may consider as a tolerably fair précis of what took place. The attack began on the 18th about ten o'clock[16] and raged furiously along the whole line, but principally at Hougoumont, a large _Métairie_ on the right of our position, which was occupied by our troops, and from which all the efforts of the enemy could not dislodge them. The slaughter was terrible in this quarter. From twelve o'clock till evening several desperate charges of cavalry and infantry were made on the rest of our line. Both sides fought with the utmost courage and obstinacy, and were prodigal of life in the extreme. But it is generally supposed that our army must have succumbed towards the evening had it not been for the arrival of Bulow's division of Prussians, followed closely by Blucher and the rest of the army, which had rallied with uncommon celerity. These moved on the right flank of the French, and decided the fortune of the day by a charge which was seconded by a general charge from the whole of the English line on the centre and left of the French. Seeing themselves thus turned, a panic, it is said, spread among the young Guard of the French army, and a cry of "_Sauve qui peut! nous sommes trahis!_" spread like wildfire. The flight became universal; the old Guard alone remained, refused quarter and perished like Leonidas and his Spartans. The Prussian cavalry being fresh pursued the enemy all night, _l'épée dans les reins_, and it may be conceived from their previous disposition that they would not be very merciful to the vanquished. Indeed, on the 15th, it is said that the French were not very merciful to them. It was like the combat of Achilles and Hector. No thought but rage and never ceasing strife Till death extinguish rage and thought and life.
