It was now daylight, and the scene in the streets was a strange one. The skirmishers darted between the trees, and the little blue-white puffs of smoke spotted the whole picture. The retiring rebels left their wounded on the ground, and these the soldiers bayoneted savagely. Shots were fired from the windows of the houses and from any shelter that offered,--a lamp-post, a pillar-box, a wounded man, an overturned cab. The rifle-fire was searching, and the streets were very bare. In their desire to get cover, to get behind something, both sides broke into the houses and dragged out chairs, tables, and piles of bedding; and though these were but little protection from the bullets, men felt less naked behind them. All this time the troops were steadily advancing, though suffering continual loss; but gradually the fire of the rebels grew hotter. More men were hurried to the scene each moment; the pressure on the flanks became severe; the enveloping enemy pressed in down the side streets, to hold which the scanty force at the President's disposal had to be further weakened. At length the rebels ceased to retreat; they had reached their guns, four of which were arranged in a row across the avenue. The Mayoralty was now but a quarter of a mile away, and Molara called on his soldiers for a supreme effort. A dashing attempt to carry the guns with the bayonet was defeated with a loss of thirty killed and wounded, and the Government troops took shelter in a side street at right angles to the main avenue. This in turn was enfiladed by the enemy, who swept round the columns and began to cut in on their line of retreat. Firing was now general along a wide half-circle. In the hope of driving the improvised artillery-men from their places, the troops forced their way into the houses on either side of the avenue, and climbing along the roofs began to fire down on their adversaries. But the rebels, repeating the manoeuvre, met them and the attempt dwindled into desperate but purposeless fighting among the chimney-pots and the skylights.
