The following obit of a fellow Kabul to Kandahar veteren may help identify Thomas's medals as seen in his Ancestry tree photos.
"KABUL-TO-KANDAHAR VETERAN DIES
Mr. Thomas Hanley, who died suddenly at the home of his daughter, Mrs. T. E. Coombe, of Rundle street, Kent Town, yesterday, aged 81, was a member of Lord Roberts's bodyguard on the famous march from Kabul to Kandahar during the Afghan war.
Mr. Hanley joined the Argyle and Sutherland Highlanders as a young man. In 1874 he went to India, and in 1876 transferred to the Gordon Highlanders. With that regiment he went through the Afghan war of 1878-79. Later, his regiment was engaged in the first Boer war.
He received the Imperial Service Medal. Among other awards he gained were the Afghan Medal with three clasps, as well as the Bronze Star for the march to the Queen's Medal for the second Boer war with four clasps; and the King's Medal for Long Service and Good Conduct."
