During the final days of the fall of Lucknow in early 1858, the 2nd Punjab Cavalry was constantly engaged in patrolling and was frequently sent short distances in pursuit of fleeing mutineers and rebels. By this time, Probyn, worn down by the rigours of continual campaigning, was invalided back to England on 18 March 1858. By now a captain, he was brevetted to major in the regular army on 24 March 1858. Probyn was brevetted to the rank of lieutenant-colonel in the Bengal Army on 15 February 1861. He was brevetted to colonel on 15 February 1866 and to major-general on 25 July 1870.
