109th Infantry


The 109th Infantry was an infantry regiment of the British [Indian Army]. The regiment traces its origins to 1768, when it was raised as the 5th Battalion, Bombay Sepoys.
The regiment's first action was during the Mysore Campaign in the Third Anglo-Mysore War. It was next involved in the Battle of Seringapatam in the Fourth Anglo-Mysore War, and next used in the Siege of Multan during the Second Anglo-Sikh War. Its last campaign in the 19th century was the Second Afghan War. During World War I it was attached to the Aden Brigade, which was formed to protect the important naval refueling point at Aden.
After World War I the Indian government reformed the army moving from single- to multi-battalion regiments. In 1922, the 109th Infantry became the 4th Battalion 4th Bombay Grenadiers. After independence it was one of the regiments allocated to the Indian Army.
