merchants’ company, he had become a citizen of the Leopoldstadt, and had served since the siege began in a free corps. Intimately conversant with the Turkish language and customs, he willingly offered himself for the dangerous office of passing through the very camp of the Turks to convey intelligence to the Imperial army. On the 13th of August, accompanied by a servant of similar qualifications, he was let out through a sally-port in the Rothenthurm, and escorted by an aide-de-camp of the Commandant as far as the palisades. He had scarcely advanced a hundred yards, when he became aware of a considerable body of horse which advanced at a rapid pace towards the place of his exit. Being as yet too near the city to escape suspicion, he hastily turned to the left and concealed himself in the cellar of a ruined house of the suburb near Altlerchenfeld, where he kept close till the tramp of the passing cavalry had died away. He then pursued his course, and, singing a Turkish song, traversed at an idle pace and with an unembarrassed air the streets of Turkish tents.

After delivering and receiving dispatches, the adventurous pair set out on their return, and after some hairbreadth escapes from the Turkish sentries, passed the palisades and re-entered the city by the Scottish gate, bearing a letter from the Duke to the following purport:—“He had received with deep emotion the intelligence of the loss of so many brave officers and soldiers, and of the sad condition of the city consequent both on this loss in action and on the epidemic. He retained his hopes that the defenders of a place so important would never relax in their noble efforts for its preservation. A considerable army was already collected for its relief. Reinforcements were daily arriving from Bavaria, Franconia, and Saxony, and the Duke was only waiting the arrival of the numerous forces of Poland, commanded by their king in person, which was to be expected by the end of August at the latest,
