Mangal Pandey comes into mind when it comes to 1857 revolt and also at that time even Bihar was under Bengal. Plus, India's independence movement was mostly driven by Hindu Bengalis and it was mostly our vision for building a better modern state, them raqibools always bitch about wanting a separate province of East Bengal and taunt Indian Bengalis by calling us Dadas and look down on us for being cheap, etc. Its funny how due to this inferority complex of raqibools, they went for Pakistan thinking Muslim Muslim bhai bhai but endup getting fucked by then Pakistani Generals.These chutya don't know in Bengal regiment most were from awadh and bihar , bihar is not north India in my opinion?
Bengalis although have many talents in many fields but as far as british indian amry goes, they didn't join it in large numbers too be honest.
