The regiment was raised on 10 December 1846 at
Hoshiarpur as the 1st Regiment of Infantry The Frontier Brigade by Major JS Hodgson. It was composed of
Sikhs, Punjabi Muslims,
Pathans and
Dogras, mostly recruited from the disbanded regiments of the
Sikh Empire following the
First Anglo-Sikh War. In 1847, it was designated 1st Regiment of Sikh Local Infantry, becoming the 1st Regiment of Sikh Infantry in 1857. In 1851, the regiment became part of the
Punjab Irregular Force, which later became famous as the Punjab Frontier Force or
The Piffers. The Piffers consisted of five regiments of cavalry, eleven regiments of infantry and five batteries of artillery besides
the Corps of Guides. Their mission was to maintain order on the Punjab Frontier; a task they performed with great aplomb. The 1st Sikh Infantry took part in numerous frontier operations besides the
Second Sikh War of 1848–49 and the Great
Indian Mutiny of 1857–58, when it fought in
Rohilkhand and
Oudh in North India. During the
Second Afghan War of 1878–80, the regiment took part in the capture of
Ali Masjid and the advance to
Jalalabad. In 1900, it went to
China to suppress the
Boxer Rebellion. ==51st Sikhs (Frontier Force)==
