The minister was anxious to comply with his request by despatching him to the army; but this official sanction was insufficient for d’Eon; he required further the consent of the King. The Comte de Broglie, whose aide-de-camp he wished to become, and who, in fact, continued to attend to the business of the secret diplomacy from the army, submitted his desire to the sovereign, and obtained the following reply:— ... I do not think we have need at present of the Sieur d’Eon; you may, therefore, take him as your aide-de-camp, and it will be all the better as we shall know where to find him in case of necessity. D’Eon was immediately appointed and started without delay for the army, where he at once entered active service. At Höxter he was entrusted with the removal of the ammunition and some of the King’s stores which had been left in the fortress: these he put on board the boats moored on the banks of the Weser, and crossed the river several times under the enemy’s fire. A little later, in an action at Ultrop, near Löft, he was wounded in the face and thigh. On November 7, 1761, when commanding the grenadiers of Champagne and the Swiss, he attacked the Scottish Highlanders, who were ambushed in the mountain gorges close to the camp of Einbeck, dislodging them and pursuing them as far as the English quarters. Lastly, at Osterwieck, when in command of a small detachment of only about a hundred dragoons and hussars, he fearlessly charged the Frankish Prussian battalion of Rhes, which had intercepted the communications of the French army near Wolfenbüttel. So sudden was his attack that the enemy, put to confusion, laid down their arms, enabling him to take eight hundred prisoners. The Prince Xavier de Saxe profited by this daring exploit in advancing his troops and occupying Wolfenbüttel. All these great feats, which d’Eon was wont to recount complacently, and which he bade his biographer, La Fortelle, relate, are attested besides by the certificate delivered to him by the Marshal and the Comte de Broglie on his leaving the army: Victor-François, Duc de Broglie, Prince of the Holy Empire, Marshal of France, Knight of the Royal Orders, Commander in Alsace, Governor of the town and castle of Béthune, and in command of the French army on the Upper-Rhine; And Charles, Comte de Broglie, Knight of the Royal Orders, Lieutenant-General of the King’s armies, and Quartermaster-General of the army of the Upper Rhine.
