thanks for adding me in to the conversation. Yeah, it is one of the endless list of battles in Sikh history where they fought to the last man against a far superior (in number) force. The most famous of the last stands is actually from time of our 10th Guru (1705) wherein 40 men defended a fort against an army of 100k (mostly hindu and muslim soldiers of the Indian govt of that time). It was an unbelieveable battle wherein Sikhs would come out of the fort in a batch of three and engage a sea of enemy, who were constrained by a narrow uphill approach to the fort. Sikh historical sources claim thousands of casualities among besiegers.
Regarding Saragarhi, I was a bit disappointed by the movie. I think it does disservice to the story due to many fictional elements. It also does not represent the Sikh regiment, known for its discipline and hardiness in a correct fashion. Believe me, Sikhs, when in uniform, need no man to motivate them to fight till the last. Anyways, this short animation in my view provides the most authentic description of the battle. Do watch if you interested in this event.
Another must read is a book by Winston Churchill,"The story of the Malakand Field Force". It details the second battle/campaign of British against Afghans. It will give chills to anyone remotely interested in wars/military. Available for free on kindle
