The next day he brought up the military engines, and without much difficulty battered down a part of the wall. But when the Macedonians attempted to force their way through the breach which had been made, the Indians repelled all their attacks with so much spirit that Alexander was obliged for that day to draw off his forces. On the morrow the Macedonians renewed their assault with even greater vigour, and a wooden tower was brought up against the wall from which the archers shot at the Indians, while missiles were discharged against them from engines. They were thus driven back to a good distance, but still their assailants were after all unable to force their way within the walls. On the third day Alexander led the phalanx once more to the assault, and causing a bridge to be thrown from an engine over to that part of the wall which had been battered down, by that gangway he led the hypaspists over to the breach—the same men who by a similar expedient had enabled him to capture Tyre. The bridge, however, broke down under the great throng which was pushing forward with eager haste, and the Macedonians fell with it. The barbarians on the walls, seeing what had happened, began amid loud cheering to ply the Macedonians with stones and arrows and whatever missiles they had ready at hand or could at the moment snatch up, while others sallying out from posterns in the wall between the towers, struck them at close quarters before they could extricate themselves from the confusion caused by the accident. _Chapter XXVII.—Massaga taken by storm—Ora and Bazira besieged_ Alexander then sent Alketas with his brigade to take up the wounded and recall to the camp the active combatants. On the fourth day another gangway on a different engine was despatched by him against the wall.
