But the 29th came and passed, with no general attack from the besiegers. A mine was sprung under the Burg ravelin, nearly completing the ruin of the work; and three or four hundred Turks attempted to establish themselves upon the remains, but were driven back again. Another mine was sprung by the Burg bastion, but no assault followed. From St. Stephen's considerable movement was noticed among the Turkish detachments on the left bank of the Danube, occasioned by the march of Lorraine's army. In the camp murmurs and dissensions ran high. The Janissaries clamoured at their lengthy detention in the trenches. They openly accused the incapacity, or worse faults, of the Vizier. There seems little doubt but that he had it in his power to have overwhelmed the defenders by a general and prolonged assault, towards the end of August. Ottoman leaders had known well how to avail themselves of the obedience and fatalist courage of their soldiers. Amurath IV., when he won back Baghdad from the Persians, Mahomet II., at the taking of Constantinople, had shown how cities could be won. Before the city of the Khalifs for three days, before the city of the Cæsars from a May sunrise till well nigh noon, had torrent after torrent of brave, devoted, undisciplined soldiers wearied the arms and exhausted the ammunition of the defenders, until the Janissaries arose, fresh and invincible for the decisive charge. Wave after wave of stormers, fed from inexhaustible multitudes, had rolled upon the besieged, and, like broken waves, had rolled back in ruin, until the last and greatest should burst in overwhelming force upon the breaches. Such an assault would have been surely successful against Vienna. But the Vizier, in vain security, pictured to himself the advantages of a surrender, which should preserve the city as a trophy of his conquest--the seat, perchance, of his sovereignty. The riches which he dreamed it to contain, he hoped to receive as his own spoil; not to yield as the booty of the army after a storm. So, while the decisive days passed, the signal for attack was delayed, except by small bodies upon single points, until the courage of his soldiers was dissipated and their confidence destroyed. On the contrary, the unexpected reprieve gave courage to the defenders. The Janissaries, on the other hand, impatiently invoked the appearance of the relieving army to end their sojourn in the trenches by the decisive event of a stricken field. Slowly, but at last, ere yet too late, that army was approaching. FOOTNOTES: [7] That is the Leopoldstadt over against Neuhausel, not the island suburb of Vienna.
