The parapet which ran round the rampart was narrow, and was not marked out along the coping with battlements and embrasures, but was built in an unbroken line of breastwork, which obstructed assailants in attempting to get over. The king then was clinging to the edge of the parapet, rather than standing upon it, warding off with his shield the darts that fell upon him from every side, for he was assailed by missiles from all the surrounding towers. Nor were the soldiers able to mount the wall under the storm of arrows discharged against them from above.[293] Still at last a sense of shame overcame their fear of the greatness of the danger, for they saw that by their hesitation the king would fall into the hands of his enemies. But their help was delayed by their hurry, for while every one strove to get soonest to the top of the wall, they were precipitated from the ladders which they overloaded till they broke, thus balking the king of his only hope. He was in consequence left standing in sight of his numerous army, like a man in a solitude, whom all the world has forsaken. _Chapter V.—Alexander is severely wounded by an arrow within the stronghold of the Sudracae—The arrow is extracted by Critobulus_ By this time his left hand, with which he was shifting his buckler about, became tired with parrying the blows directed against him from all round, and his friends cried out to him that he should leap down, and were standing ready to catch him when he fell. But instead of taking this course, he did an act of daring past all belief and unheard of—an act notable as adding far more to his reputation for rashness than to his true glory. For with a headlong spring he flung himself into the city filled with his enemies, even though he could scarcely expect to die fighting, since before he could rise from the ground he was likely to be overpowered and taken prisoner. But, as luck would have it, he had flung his body with such nice poise that he alighted on his feet, which gave him the advantage of an erect attitude when he began fighting. Fortune had also so provided that he could not possibly be surrounded, for an aged tree which grew not far from the wall, had thrown out branches thickly covered with leaves, as if for the very purpose of sheltering the king. Against the huge bole of this tree he so planted himself that he could not be surrounded, and as he was thus protected in rear, he received on his buckler the darts with which he was assailed in front; for single-handed though he was, not one of the many who set upon him ventured to come to close-quarters with him, and their missiles lodged more frequently in the branches of the tree than in his buckler.
