He expired in 1798 when Hari Singh was only seven years of age and was thus looked after with care and caution by his maternal uncle who took him to his house. In those days training in the feats of war was deemed necessary and physical education attracted much attention. Accordingly, Hari Singh who was physically quite stout and strong and impressive too in appearance when grew up, learnt the art of warfare. It is said that he was indefatigable and could sit on horse back for long hours. Hari Singh received his preliminary education in languages of Gurmukhi, Urdu, Persian. Baron Charles Hugel states that Hari Singh besides his general knowledge about the statistics of many of the European states, was well versed in Persian. He impressed him extremely with his overall achievements.
