20th Indian Infantry Brigade

The 20th Indian Infantry Brigade was an Infantry formation of the Indian Army during both World Wars. It was formed in September 1940, by the conversion of the Khojak Brigade and assigned to the 9th Indian Infantry Division. In April 1941, they were transferred to the 10th Indian Infantry Division and took part in the Anglo-Iraqi War, Syria-Lebanon campaign and the Anglo-Soviet invasion of Iran. Moving to Egypt in June 1942, the brigade was overrun and largely destroyed at Gambut 18 June 1942. The brigade was reformed in the Nile Delta and returned to the 10th Division.
