Almost everywhere the city forces were worsted. But it took time. It was not an utter rout. A hundred thousand personal combats. Inconceivable sanguinary warfare this! All indoors! * * * * * When the local ventilating system was broken, Turber must have known it at once. Within an hour the type of fighting in this section was wholly changed. The Turberites had fought their way northward up Broadway with the city forces scattering east and west as they advanced. The attackers permeated every passage and tunnel and room. Thousands of them must have wandered aimlessly, lost. Wandering--killing and plundering as they went. The civilians were nearly all out of this area now. A wedge of the Turberites reached what in my day was Columbus Circle. There seemed leaders among them to direct what they were after. They worked their way northward, and then shifted to the east--toward the corridor-street where our tower-space was located. The danger was recognized by the high command. Police troops were withdrawn from the Hoboken section, where similar scenes were transpiring south of the main city power station, and troops were brought from other sections. Our lines on the roof over the harbor were weakened--but there seemed little activity up there. The strengthened police squads fought their way into mid-Broadway. The upflung wedge of Turberites was cut off. Inhuman with their heedlessness, their reckless thirst for blood; but here for the first time we saw them falter. Cut off from possible retreat, a panic swept them. A thousand or more of them tried to get back. The city troops drove them out of the Broadway corridor and hunted them down as they tried to escape into the honeycomb of the city. We gained ground here for a time. But new mobs of the enemy came pouring northward. All this within an hour or two. The ventilating system of Mid-Manhattan was failing. Turber knew it--and presently the whole character of the fighting there changed. The Turber mobs began withdrawing from this newly captured area. The air was turning fetid, but the police pursued the retreating Turberites as best they could. * * * * * The Manhattan exits of the vehicular tunnels under the harbor network of islands were all held by Turber now. From them a new horde of his fighters began pouring. Strange figures in black hoods with goggling mouth tubes. They came prowling in the north-south corridors. They worked their way north. The fetid air did not seem to impede them. They held strange round objects in their hands. They threw the objects, which shattered and spread heavy-lying chlorine gas. And mustard gas. The corridors and rooms choked up--with fumes and the fallen bodies of our police. The strange Turberite figures prowled like ghouls among them. Strange familiar warfare! Alan and I recognized it. These grenade-like missiles--these gas bombs--these figures with gas masks--
