The British-Indian expedition led by Sir James…
March 1857 CE
The British-Indian expedition led by Sir James Outram is successful against the Persians, who sue for peace in March 1857.
A treaty is signed, asking for no concessions except recognition of Afghan boundaries and Persian evacuation from Afghan soil.
The British governor general of India at the time of the agreement with Afghanistan states in a memorandum that the British would never again intervene in Afghan internal affairs or send an army across its borders unless Herat is besieged, and then only with Afghan consent.
He goes so far as to argue in favor of the Afghan absorption of Herat.
