[1] Probably because of conditions imposed by his family who still supported him with funds, Pottinger kept his title secret but in 1860 it was discovered by the inspector-general of police, John McLerie, and promotion came rapidly.
Sued, he received a public rebuke from the New South Wales premier, Charles Cowper, for his "highly discreditable" behaviour.
Criticised for his failure to send an adequate guard with the escort, and his return without prisoners, Pottinger was praised by others for his determination and endurance.
Early in January 1865, hoping to lure Hall and his associate, fellow bushranger John Dunn, into the open, Pottinger rode in the Wowingragong races, in breach of police regulations.
Despite his claim that his action "fully warranted the discretionary departure in point from the letter (tho' not the spirit)" of the regulation, he was dismissed from the police force on 16 February 1865.
On 5 March 1865, at Wascoe's Inn in the Blue Mountains, while boarding a moving coach on his way to Sydney to seek redress, Pottinger accidentally shot himself in the upper abdomen.
He recovered sufficiently to be moved to the Victoria Club in Sydney, but he died intestate on 9 April 1865, and was buried at St Jude's Anglican Church, Randwick.
