Zulu is quite a good movie

One of my all time favorite war movies. It was Michael Caine's first big acting role and he and Stanley Baker were excellent. The battle was top notch and it was really cool seeing what late-19th century fighting might have looked like.

The Anglo-Zulu War was fought in 1879 between the British and the Zulu Empires in modern day South Africa. The war is famous for the Zulu's surprise victory at Isandlwana and the Battle of Rorke's Drift, where less than 200 British soldiers defeated a force of 4,000 Zulu warriors. Zulu depicts the latter battle and a prequel, Zulu Dawn, centers on the former. The war ended the same year it started with the fall of the Zulu Empire and its annexation into the British Empire.

Eleven Victoria Crosses were awarded to survivors of Rorke's Drift and even if the movie isn't 100% historically accurate, the medals were definitely deserved.
