The crowd was gathering unto itself a kind of fury that greatly resembled courage. Those that were behind pushed and those that were in front could no longer retreat. Blood had begun to flow more freely and the groans of the wounded had roused the bellicose instincts of those whose skin was still whole. One or two of the more venturesome had made close and gruesome acquaintance with the silent but swift Bucephalus, whilst from the market place in the rear the numbers of the crowd thus packed in this narrow street corner swelled dangerously. The new comers did not know what had happened before their arrival. They could not see over the heads of the crowd what was going on at this moment. So they pushed from behind and the three combatants with their backs against the wall had much difficulty in keeping a sufficiently wide circle around them to allow their swords free play. Already Socrates, dizzy from the blood that was streaming down his sharp, hooked nose, had failed to keep three of his foremost assailants at bay: he had been forced to yield one step and then another, and the elbow of his sword arm was now right up against the wall. Pythagoras, too, was equally closely pressed, and Diogenes had just sent an over bold lout sprawling on the ground. The noise was deafening. Every one was shouting, many were screaming or groaning. The town guard, realizing at last that a tumult of more than usual consequence was going on in some portion of the city, had decided to go and interfere; their slow and weighty steps and the clang of their halberds could be heard from over the Grootemarkt during the rare moments when shouts and clamour subsided for a few seconds only to be upraised again with redoubled power. Then suddenly cries of "Help!" were raised from the further end of Dam Straat, there where it debouches on the bank of the Spaarne. It was a woman's voice that raised the cry, but men answered it with calls for the guard. The tumult in front of the postern gate now reached its climax, for the pressure from behind had become terrible, and men and women were being knocked down and trampled on. It seemed as if the narrow street could not hold another human soul, and yet apparently more and more were trying to squeeze into the restricted space. The trampled, frozen snow had become as slippery as a sheet of glass, and if the guard with their wonted ponderous clumsiness charged into the crowd with halberds now, then Heaven help the weak who could not elbow a way out for themselves; they would be sure to be trampled under foot.
