When Leopold supplicated Sobieski to come to his aid, Louis XIV tried to divert him from it; he reassured him upon the projects of the Turks by a letter of the Sultan, he made him see his real enemies in Austria, Brandenburg, and that power of the North, which the Dutch gazettes had begun to call "His Russian Majesty"; he reminded him, in fine, that the house of Austria, saved by the French on the day of St. Gothard, had testified its gratitude to them by allowing the victors to die of hunger and by envenoming their difference with the Porte. But it was all useless; hatred of the infidels prevailed, and the Polish squadrons hurried to the deliverance of Vienna. Count Rudiger de Starhemberg was made commandant of the city, and showed himself alike bold and energetic in everything that could contribute to its defence. The Turkish camp encircled Vienna and its suburbs, spreading over the country all round to the distance of six leagues. Two days afterward, Kara Mustapha opened the trenches, and his artillery battered the walls in order to make a breach. Great efforts, moreover, were made in digging mines, with the design of blowing up bastions or portions of the wall, so that the city might be carried by assault, wherein the Turks hoped to find an immense booty. But the besieged made an obstinate defence, and repaired during the night the damage done on the previous day. During sixty days forty mines and ten counter-mines were exploded; the Turks delivered eighteen assaults, the besieged made twenty-four sorties. Each inch of ground was only obtained by dint of a hard and long struggle, in which an equal stubbornness both in attack and defence was exhibited.
