After the search began, the master of the house in which he might be found would be hung at his own door, his family thrown into prison, his goods confiscated, his house razed to the ground, without any form of trial whatever.
This proclamation had the effect expected by the duke: whether the man in whose house Catinat was concealed grew frightened and asked him to leave, or whether Catinat thought his best course would be to try and get away from the town, instead of remaining shut up in it, he dressed himself one morning in suitable clothes, and went to a barber's, who shaved him, cut his hair, and made up his face so as to give him as much the appearance of a nobleman as possible; and then with wonderful assurance he went out into the streets, and pulling his hat over his eyes and holding a paper in his hand as if reading it, he crossed the town to the gate of St.Antoine.He was almost through when Charreau, the captain of the guard, having his attention directed to Catinat by a comrade to whom he was talking, stopped him, suspecting he was trying to escape.

Catinat asked what he wanted with him, and Charreau replied that if he would enter the guard-house he would learn; as under such circumstances any examination was to be avoided, Catinat tried to force his way out; whereupon he was seized by Charreau and his brother-officer, and Catinat seeing that resistance would be not only useless but harmful, allowed himself to be taken to the guard-room.
He had been there about an hour without being recognised by any of those who, drawn by curiosity, came to look at him, when one of the visitors in going out said he bore a strong resemblance to Catinat; some children hearing these words, began to shout, "Catinat is taken! Catinat is taken!" This cry drew a large crowd to the guard-house, among others a man whose name was Anglejas, who, looking closely at the prisoner, recognised him and called him by name.
Instantly the guard was doubled, and Catinat searched: a psalm-book with a silver clasp and a letter addressed to "M.

Maurel, called Catinat," were found on him, leaving no doubt as to his identity; while he himself, growing impatient, and desiring to end all these investigations, acknowledged that he was Catinat and no other.
He was at once taken to the palace, where the Presidial Court was sitting, M.de Baville and the president being occupied in trying Ravanel, Villas, and Jonquet.

On hearing the news of this important capture, the intendant, hardly daring to believe his ears, rose and went out to meet the prisoner, in order to convince himself that it was really Catinat.
From the Presidial Court he was brought before the Duke of Berwick, who addressed several questions to him, which Catinat answered; he then told the duke he had something of importance to impart to him and to him alone.

The duke was not very anxious for a tete-a-tete with Catinat; however, having ordered his hands to be securely bound, and telling Sandricourt not to go away, he consented to hear what the prisoner had to say.
Catinat then, in the presence of the duke and Sandricourt, proposed that an exchange of prisoners should be made, the Marechal de Tallard, who was a prisoner of war in England, being accepted in his place.
