It is certain that Napoleon made mistakes during the war with Russia, that Alexander committed blunders in the war in India, that Caesar made mistakes in the war in Africa, that Cyrus was at fault in the war in Scythia, and that Javert blundered in this campaign against Jean Valjean. He was wrong, perhaps, in hesitating in his recognition of the exconvict. The first glance should have sufficed him. He was wrong in not arresting him purely and simply in the old building; he was wrong in not arresting him when he positively recognized him in the Rue de Pontoise. He was wrong in taking counsel with his auxiliaries in the full light of the moon in the Carrefour Rollin. Advice is certainly useful; it is a good thing to know and to interrogate those of the dogs who deserve confidence; but the hunter cannot be too cautious when he is chasing uneasy animals like the wolf and the convict. Javert, by taking too much thought as to how he should set the bloodhounds of the pack on the trail, alarmed the beast by giving him wind of the dart, and so made him run. Above all, he was wrong in that after he had picked up the scent again on the bridge of Austerlitz, he played that formidable and puerile game of keeping such a man at the end of a thread.
