English: Pen and ink drawing of British troops crossing the Sutlej River in boats by Sir Henry Yule, dated 10 February 1846. Inscribed on the front in water-colour is: 'Passage of the Sutlej. Feby 10, 1846.' Sir Henry Yule (1820-1889) served with the Bengal Engineers in India from 1840 to 1862. From 1845 to 1849 he worked in the North West Provinces restoring and developing the old Mughal irrigation system. Work on this project was interrupted by the First and Second Anglo-Sikh Wars (1845-6 and 1848-9) in which he participated. Sir Henry Yule is remembered for his work on the 'Hobson-Jobson' (London, 1886), a glossary of Anglo-Indian colloquial words and phrases, as well as other works on the history and geography of Asia. The Sutlej, or 'many-channelled' is the largest of the five rivers from which the Punjab derives its name.
