That's very interesting, I know about the Swiss Pikemen (from Age of Empires, I think!).
I'm a Sikh, our warrior culture is immense and something that people should really read about, purely because it's so interesting! Our entire history is embroiled in last stands, it would make Leonidas proud.
For example, the Battle of Saragarhi 1897.
21 Sikhs against 10,000 Afghans. Known as one of the greatest last-stands in all of military history, every single man gave his life, yet very few people know about the battle. Furthermore, unlike many of the older last-stands, this one was very accurately recorded, partly due to the nature of the battle and also due to the fact it was fairly recent.
