While Gavroche was deliberating, the attack took place, abruptly and hideously. The attack of the tiger on the wild ass, the attack of the spider on the fly. Montparnasse suddenly tossed away his rose, bounded upon the old man, seized him by the collar, grasped and clung to him, and Gavroche with difficulty restrained a scream. A moment later one of these men was underneath the other, groaning, struggling, with a knee of marble upon his breast. Only, it was not just what Gavroche had expected. The one who lay on the earth was Montparnasse; the one who was on top was the old man. All this took place a few paces distant from Gavroche.

The old man had received the shock, had returned it, and that in such a terrible fashion, that in a twinkling, the assailant and the assailed had exchanged roles.

“Here’s a hearty veteran!” thought Gavroche.

He could not refrain from clapping his hands. But it was applause wasted. It did not reach the combatants, absorbed and deafened as they were, each by the other, as their breath mingled in the struggle.
