The
Armoury Raid, also known as Chittagong uprising, was an attempt on
18 April 1930 to raid the armoury of police and auxiliary forces from the Chittagong armoury in the Bengal
Province of British India (now in Bangladesh) by armed Indian independence
fighters led by Surya Sen. On returning to Chittagong in
1918, he organized Jugantar and joined the Umatara School at Chandanpore.
Hence, the name ‘Masterda’ (Elder Brother).
