* The first peace treaty, initiated by Edwardes and signed in March 1855, bound the Afghans to be ‘friends of our friends and enemies of our enemies’ and in return the East India Company promised not to expand its borders westward. Dost Mohammed signed a supplementary treaty in January 1857, declaring that he had made an irrevocable alliance with the British and that, ‘happen what may, I will keep it faithfully till death’.
