Which battle is depicted in the 1964 film Zulu?

pattiehartland5000, it is in South Africa home of the Zulu nation

Considered progressive for its day because the Zulus are portrayed with respect.

anyone who watched the film should know this!! unfortunately I didn't, but I still knew the answer?! don't know how, but I did.. perhaps it was due to the poem about it.. don't ask me how it goes!!
