    A poet born on this day in 1809, penned the lines quoted

    Someone had blundered.
       Theirs not to make reply,
       Theirs not to reason why,
       Theirs but to do and die.
    Who was the poet and what poem are the lines from?

    Answer: Alfred, Lord Tennyson and The Charge of the Light Brigade

    Alfred Tennyson, 1st Baron Tennyson, was an English poet and Poet Laureate during Queen Victoria’s reign. He is known for his short lyrics, classical mythological themes, and blank verse, with many of his phrases becoming commonplace in the English language.
    The lines quoted were from The Charge of the Light Brigade which is a narrative poem by Tennyson (The full poem is shown bellow). It describes the Charge of the Light Brigade, a disastrous British cavalry attack against heavily defended Russian troops at the Battle of Balaklava in October 1854 during the Crimean War. The suicidal assault placed the British light horse brigade, commanded by the Earl of Cardigan, against a Russian infantry and cavalry defence supported by heavy artillery batteries that commanded three sides of a narrow valley.


    The Charge of the Light Brigade

    ALFRED, LORD TENNYSON

    I
    Half a league, half a league,
    Half a league onward,
    All in the valley of Death
       Rode the six hundred.
    “Forward, the Light Brigade!
    Charge for the guns!” he said.
    Into the valley of Death
       Rode the six hundred.

    II
    “Forward, the Light Brigade!”
    Was there a man dismayed?
    Not though the soldier knew
       Someone had blundered.
       Theirs not to make reply,
       Theirs not to reason why,
       Theirs but to do and die.
       Into the valley of Death
       Rode the six hundred.
       
    III
    Cannon to right of them,
    Cannon to left of them,
    Cannon in front of them
       Volleyed and thundered;
    Stormed at with shot and shell,
    Boldly they rode and well,
    Into the jaws of Death,
    Into the mouth of hell
       Rode the six hundred.

    IV
    Flashed all their sabres bare,
    Flashed as they turned in air
    Sabring the gunners there,
    Charging an army, while
       All the world wondered.
    Plunged in the battery-smoke
    Right through the line they broke;
    Cossack and Russian
    Reeled from the sabre stroke
       Shattered and sundered.
    Then they rode back, but not
       Not the six hundred.

    V
    Cannon to right of them,
    Cannon to left of them,
    Cannon behind them
       Volleyed and thundered;
    Stormed at with shot and shell,
    While horse and hero fell.
    They that had fought so well
    Came through the jaws of Death,
    Back from the mouth of hell,
    All that was left of them,
       Left of six hundred.

    VI
    When can their glory fade?
    O the wild charge they made!
       All the world wondered.
    Honour the charge they made!
    Honour the Light Brigade,
       Noble six hundred!
