Solution:
Mangal Pandey, the renowned Indian soldier and a key figure in the Indian Rebellion of 1857, belonged to the 34th Bengal Native Infantry regiment. He was stationed in Barrackpore, West Bengal, and it was there that he sparked the rebellion by refusing to use the newly introduced Enfield rifle cartridges rumored to be greased with animal fat, which was offensive to both Hindu and Muslim soldiers. His courageous act of defiance against this perceived disrespect to religious beliefs marked the beginning of a significant uprising against the British East India Company's rule. Mangal Pandey's actions in the 34th Bengal Native Infantry regiment played a pivotal role in the events that unfolded during the Indian Rebellion of 1857.
