The Bengal Engineer Group (BEG) or the Bengal Sappers or Bengal Engineers as they are informally known, are remnants of British Indian Army's Bengal Army of the Bengal Presidency in British India; now a regiment of the Corps of Engineers in the Indian Army. The Bengal Sappers have their regimental centre at Roorkee Cantonment in Haridwar district, Uttarakhand. The Bengal Sappers are one of the few remaining regiments of the erstwhile Bengal Presidency Army and survived the Rebellion of 1857 due to their sterling work in the recapture of Delhi and other operations in 1857–58. The troops of the Bengal Sappers have been a familiar sight for over 200 years in the battlefields of British India with their never-say-die attitude of Chak De and brandishing their favourite tool the hamber.
