It was not until the later stages of the battle that the famous Charge of the Light Brigade took place. In fact it was caused by confusion of orders. From his position on the Sapoune Heights, Lord Raglan could see that the Russians were about to carry away the captured guns from the Causeway Heights. Raglan therefore ordered Lord Lucan, the commander of the Cavalry Division, to launch the Light Brigade to retake the guns. From his position in the valley Lucan could not see the guns. When he asked for further clarification from Captain Nolan, the ADC who had brought the message, Nolan pointed not to the guns on the Causeway Heights, but to a Russian Battery at the end of the valley. Having received the clarification he required he directed Lord Cardigan, his brother-in-law and Commander of the Light Brigade, to advance down the valley.
On orders Cardigan advanced the five regiments of the Light Brigade towards the line of Russian guns at a trot. The first salvo was fired when the brigade had advanced only 200 yards. Each subsequent salvo took a heavy toll on the 17th, who were positioned forward left in the Brigade, but the advance continued unabated with the gaps in the line being filled quickly. As they neared the guns, the Light Brigade broke into a charge, and were met within eighty yards by a final salvo. The 17th, led by Captain Morris, swept down on the enemy, carrying the guns and driving the Russian cavalry, who were massed behind the guns, back in disarray. “Half a dozen of us leaped in among the guns, and I with one blow brained a Russian gunner.” (Private John Vahey, Regimental butcher). The force was however too small to maintain the position unaided and were forced to withdraw back up the valley, again under constant musket and artillery fire from the flanking Heights, and harassed by Cossacks who rode down among them.
Of the 147 17th Lancers that charged, only 38 answered the roll call after the battle. For their gallant actions that day, three Victoria Crosses were awarded to members of the Regiment. Although the 17th remained in the Crimea for the rest of the campaign they did not play a major role in any of the remaining battles, which were predominantly infantry affairs.
