Text of the Poem
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. "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. 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. Flashed all their sabers bare, Flashed as they turned in air Sab'ring 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 saber stroke Shattered and sundered. Then they rode back, but not, Not the six hundred. 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. When can their glory fade? O the wild charge they made! All the world wondered. Honor the charge they made! Honor the Light Brigade, Noble six hundred!
— William Delaney
"Volleyed" means a number of cannons all firing at once. "Thundered" would be the sound of these cannons after the bright flash of the cannon fire. The sound would be heard an appreciable instant after the flash because light travels faster than sound. The word "thundered" suggests a comparison with the flash of lightning and the thunder which follows it.
