ennyson's poem, published December 9, 1854 in The Examiner[1], praises the Brigade, "When can their glory fade? O the wild charge they made!", while mourning the appalling futility of the charge: "Not tho' the soldier knew / Some one had blunder'd ... Charging an army while / All the world wonder'd:". According to his grandson Sir Charles Tennyson, Tennyson wrote the poem in only a few minutes after reading an account of the battle in The Times. As poet laureate he often wrote verses about public events. It immediately became hugely popular, even reaching the troops in the Crimea, where it was distributed in pamphlet form at the behest of Jane, Lady Franklin.[2]
Each stanza tells a different part of the story, and there is a delicate balance between nobility and brutality throughout. Although Tennyson's subject is the nobleness of supporting one's country, and the poem's tone and hoofbeat cadences are rousing, it pulls no punches about the horror of war: "Cannon to right of them, /Cannon to left of them, / Cannon behind them / Volley'd & thunder'd". With "into the valley of Death" Tennyson works in resonance with "the valley of the shadow of Death" from Psalm 23; then and now, it is often read at funerals. Tennyson's Crimea does not offer the abstract tranquil death of the psalm but is instead predatory and menacing: "into the jaws of Death" and "into the mouth of Hell". The alliterative "Storm'd at with shot and shell" echoes the whistling of ball as the cavalry charge through it. After the fury of the charge, the final notes are gentle, reflective and laden with sorrow: "Then they rode back, but not / Not the six hundred".

Battle of Balaclava during the Crimean War

I think i did that for my English GCSE's but i cant remember off the top of my head what i wrote.

You could do how the author portrayed the soldiers and then say how it was seen now compared to back then.
So back then they were seen as heroes for that charge. However we know now they ran the wrong way and that lead to there death.

why not read the poem?

might be a good place to start. then go to wikipedia
