Yeah I have seen that stuff, and that battle for instance is hardly unique, you don’t have to go back to Thermopylae for that kind of 1800s bravery just look at everyone else, the Brits, the Texans the French at Camerone (a day I toast every April 30th), there are many such battles to the death.
I don’t understand why this little cult considers Sikhs to be some super soldiers, where do they rank with the crack Western units over the years, especially the last hundred?
The thing is it's in their religion. Among their primary beliefs are to fight for the rights of everyone, and to be ready to die doing it. It doesn't make them super soldiers necessarily, but it does make them very quick to fight to the death doing God's work. All baptized Sikhs carry a dagger, the kirpan, traditionally not for offense or even necessarily self-defense, but in case it is needed to defend someone from injustice.
Even the name for a baptized Sikh is a "saint-soldier" and he becomes part of the Army of God. This isn't a figurative army, such as spreading the word or such. They mean it literally, be ready to fight to the death to protect any of God's people (which to them means every human).
