For the City Hall had awakened and was conferring by telephone with the Federal command and taking measures for defence.
Then into the expectant hush came a great crash and uproar, the breaking down of the Brooklyn Bridge, the rifle fire from the Navy Yard, and the bursting of bombs in Wall Street and the City Hall.
There came, too, longer and longer descriptions of the smashing up of the City Hall and the Navy Yard, and people began to realise faintly what those brief minutes of uproar had meant.
After the smashing of the City Hall and Post-Office, the white flag had been hoisted from a tower of the old Park Row building, and thither had gone Mayor O'Hagen, urged thither indeed by the terror-stricken property owners of lower New York, to negotiate the capitulation with Von Winterfeld.
Then down they had come at last to hover over City Hall Park, and it had crept in upon his mind,, chillingly, terrifyingly, that these illuminated black masses were great offices afire, and that the going to and fro of minute, dim spectres of lantern-lit grey and white was a harvesting of the wounded and the dead.
