Herat (Perso-Afghan Wars).
On November 22, 1837, Mohamed, Shah of Persia, laid siege to the city, which was held by an Afghan garrison, under Yar Mohamed. After a somewhat desultory siege, an attempt was made to storm the place, June 24, 1838, when the Persians were repulsed with a loss of 1,700 men. From this time a tacit armistice existed till September 9, when the Shah withdrew his army.
