, 1836. He fought in the
Siege of Bharatpur in January 1826. In 1827, while stationed at
Agra, he and a fellow British soldier Richard Potter deserted and traveled through parts of the
Punjab that were under British control at that time. To avoid capture, it was at this time that Lewis began to go by the alias Charles Masson while Potter went by John Brown. At
Ahmadpur, they were rescued by the American
Josiah Harlan and commissioned as mounted orderlies in his expedition to overthrow the regime in
Kabul, Afghanistan. Not long afterward, near
Dera Ghazi Khan, Masson deserted Harlan. While with Harlan, Masson and Brown pretended to be Americans to further lessen the chance of being caught as deserters. Masson was so successful in claiming to be from Kentucky that long after his death he was still being described as an American. Between 1833 and 1838, Masson excavated over 50 Buddhist sites around Kabul and
Jalalabad in south-eastern Afghanistan, amassing a large collection of small objects and many coins, principally from the site at
Bagram (the ancient
Alexandria on the Caucasus), north of Kabul. From 1827, when he deserted, to his return to England in 1842, it is estimated that Masson collected around 47,000 coins. Masson was the first European to see the ruins of
Harappa, described and illustrated in his book
Narrative of Various Journeys in Balochistan, Afghanistan and The Punjab. He also visited the
North-West Frontier Province and
Balochistan, serving as an agent of the East India Company. In the 1930s, the
French Archaeological Delegation in Afghanistan (
Délégation archéologique française en Afghanistan, DAFA) found unexpected evidence of an earlier European visitor scribbled in pencil on the wall of one of the caves above the 55 meter Buddha at
