East India Company. The 13th Light Infantry returned to garrison duty in India. From 1826 to 1838, they were stationed in Baharampur, Danapur, Agra and Karnal. First Anglo-Afghan War In 1837, Persian troops, allied to the Russians, occupied the Herat region of Afghanistan. The British, who feared Russian intervention in the area, decided to remove the emir of Afghanistan, Dost Muhammad, and to replace him with a pro-British monarch, Shuja Shah Durrani. Accordingly, an expeditionary force, known as the "Army of the Indus", was formed. The 13th Light Infantry formed part of the invasion force, joining the other units in November 1838. The army passed into Afghanistan in March 1839, taking Kandahar in April without resistance. The 13th took part in the decisive victory at Ghazni in July 1839. The British initially achieved their objective of enthroning Shuja in August 1839. The 13th formed part of the occupation force that attempted to enforce the rule of the new monarch; but, in October 1841, a popular uprising against Shuja broke out. The 13th found itself engaged in operations against the rebels who had overthrown Shuja and taken the capital, Kabul. In November 1841, the regiment was forced to retreat to the fortified town of Jalalabad. The town was soon encircled, leading to a lengthy siege. In April of the following year, the garrison, under the command of Sir Robert Sale of the 13th, broke the siege and defeated the Afghan forces under Akbar Khan. Although the war, which ended in October 1842 with the return of the Army of the Indus to India, was essentially a reverse for the British forces, battle honours and campaign medals were awarded. 13th (1st Somersetshire) (Prince Albert's Light Infantry) Regiment of Foot The conduct of the 13th at Jalalabad was officially rewarded on 26 August 1842, when Prince Albert offered his patronage to the regiment and permitted his name to be used in its title, becoming the 13th (1st Somersetshire) (Prince Albert's Light Infantry) Regiment of Foot. At the same time, the regimental facings were changed from yellow to (royal) blue, and the badge of a mural crown with a scroll inscribed "Jellalabad" was granted for display on the colours and uniform of the regiment. The unit was also honoured with the firing of a twenty-one gun salute at each army station it passed on its return to India. The 13th Light Infantry returned to
