The states of the Landgraviate were assembled on this important occasion, and such measures taken as were judged necessary to maintain the religion and constitution of the country, against any future attempt to subvert them. The Hereditary Prince was excluded from all share in the education of his sons, who were put under the tuition of the Princess Mary of Great Britain, his first wife, living at that time separate from her husband. The eldest son, upon his father’s accession to the Landgraviate, was put in possession of the county of Hanau; so that the inhabitants have felt no inconveniency from the change of their Prince’s religion. And as he himself has reaped no earthly advantage, either in point of honour or profit, by his conversion, it is presumable, that his Highness’s hopes are now limited to the rewards which may await him in another world.

This Prince keeps on foot 16000, men in time of peace, disciplined according to the Prussian plan, the Landgrave himself having the rank of Field Marshal in the Prussian army. The Prince is fond of exercising them; but not having a house on purpose, as the Prince of Hesse Darmstadt has, he takes that amusement when, the weather is very bad in the dining-room of his palace, where I have frequently seen two or three hundred of the first battalion of guards perform their manœuvres with all possible dexterity.

The Prince of Saxe-Gotha, brother to the late Princess of Wales, has a regiment in the Landgrave’s service, and resides at Cassel.

The person who has the chief management in military affairs, is General Scliven, a man of an exceeding just and accurate understanding, which he has finely cultivated by reading and reflection.

I have the happiness to be intimately acquainted with many other officers in this service.—An open manner, and undesigning civility, distinguish the German character; qualities which naturally banish reserve, and inspire confidence. And what makes the conversation of these gentlemen still more agreeable and interesting to me, is the justice they seem fond of rendering to the bravery of the British troops with whom they served. They always mention the names of Granby, Waldgrave, and Kingsley, with the highest encomiums, and speak with affectionate regard of some officers with whom they were more intimately acquainted, particularly Mr. Keith, now at Vienna, and Colonel John Maxwell, whom they applaud as one of the bravest and most active officers that served in the allied army; and seem fond of mentioning instances of the amazing intrepidity of the British grenadiers whom he commanded.

Besides those actually in the Landgrave’s service, there are some other persons of note who reside at Cassel. I sometimes pass an afternoon with old General Zastrow, who had the command of the garrison of Schweidnitz, when it was surprised by the Austrian general Laudohn.

If you recollect, that important place had been taken from the Prussians in the year 1757, by Count Nadasti. It was blockaded by the King of Prussia in the winter of that same year, and surrendered to him in spring 1758, after one half of the garrison had fallen in defending the place. In the year 1761, Laudohn retook it almost in sight of the Prussian monarchy by the most brilliant coup-de-main that perhaps ever was struck.

The King’s army and Laudohn’s were both in the neighbourhood of Schweidnitz. The latter could not attempt a regular siege, while he was watched by such an enterprising enemy. But observing that the King had moved at a greater distance than usual from the town, and knowing that more than one half of the garrison had been drafted, he resolved on an enterprise as bold as it was sagacious. One morning early this vigilant commander, taking the advantage of a thick fog, marched his army to the town, of Schweidnitz in four divisions. Scaling-ladders were applied to the ramparts, and some of the Austrians had actually entered the town, before they were observed by the centinels.

The garrison, being at last roused, attacked the assailants in a furious manner.—The confusion was increased by the blowing up of a powder magazine, which destroyed great numbers on both sides. The Governor was taken prisoner, fighting sword in hand on the ramparts, and the town surrendered.
