Wis. Stat. § 898.20
The going at large of any prisoner who shall have executed such bond or of any prisoner who would be entitled to the liberties of any jail, upon executing such bond, within the limits of the liberties of the jail of the county in which the prisoner shall be in custody, shall not be deemed an escape of such prisoner; but in case any such prisoner shall go at large without the jail liberties of such county, without the assent of the party at whose suit such prisoner shall be in custody, the same shall be deemed an escape and forfeiture of the bond so executed; and the sheriff in whose custody such prisoner shall have been shall have the same authority to pursue and retake such prisoner as if such escape had been made from the jail.
