In the 1830s, British activity focused on India, consolidating their posi-
tion in regions in which they were already dominant, as well as expand-
ing thei r power into new areas. Mysore was gained in 1831, and Karachi
fell to amphibious attack in 1839. That year, in what was a major exten-
sion of British commitment and capability, the first war with an East
Asian power began. The Opium War of 1839–1842 arose from the Chinese
attempt to enforce their prohibition on the import of opium, the pro-
fits from which were important to the economy of British India, while
the seizure of op ium held by British merchants and their expulsion from
Canton led to pressure within Britain for a response. The demand for

key coastal positions, and China cede d Hong Kong by the Treaty of
Nanjing of 1842. Also in 1839, Aden was annexed, for the first time by a
European power, giving Britain a key position where the Red Sea met
the Indian Ocean.
In the 1840s, conflict again focused on India, where there was major
expansion t o the northwest , although also major difficulties. In Afghani-
stan, where policy was motivated by a desire to contain Russian expan-
sion, support for an unpopular client ruler was initially successful, and,
in 1839, the major towns of Kandahar, Ghazni, and Kabul were easily cap-
tured. In 1841, however, a general revolt was mishandled. When the
poorly led B ritish force retreated from Kabul toward India in January
1842, it was delayed by snow and destroyed in the mountain passes by
Ghilzai trib esmen. Major-General William Elphinstone, who commanded
the retreat, h ad fought with grea t credit at Waterloo, but by 1842 he was
elderly and infirm, as well as poorly prepared. A British force, the ‘‘Army
of Retribution,’’ reoccupied (and sacke d) Kabul that autumn in a punitive
campaign, but it was then deemed prudent to withdraw swiftly.

The
failure to establish garrison control on the Indian model, w as followed ,
however, by a successful policy of containment, with the diplomatic
isol ation of Afghanistan and the strengthening of the Indian border, and
not by an Afghan invasion of northern India comparable to that in the
1750s.
In contrast, farther south, victories over the Baluchis at Miani, Umarkot,
and Mirpur Khas in 1843—smaller infantry forces, supported by cavalry
and horse artillery, successfully attacking opposing lines—led to the con-
quest of Sind by Sir Charles Napier. That year, Gwalior also was overrun,
with battles at Maharajpur and Gwa lior. To the northwest of British India,
the British also fought the Sikhs of the Punjab in two hard-fought strug-
gles.

victories at Mudki (1845), Firozshah (1845), and Sobraon (1846) owed
much to infantry actions with the bayonet. Thomas Pierce recorded,
