Unbeknownst to Pearson, calamity struck a hundred miles to the north when nearly half of No. 3 Column is destroyed during a catastrophic battle at a mountain called Isandlwana. Despite the garrison at Rorke's Drift subsequent repelling of the Zulu onslaught, the entire invasion is left in tatters. Over a thousand imperial soldiers now lie dead, in a war which the Crown never authorised or wanted.
Over the coming days, the Zulus surround the fort at Eshowe, cutting off all communications and resupply efforts. With the British Empire now reluctantly committed to war, reinforcements are dispatched from England. In a race against time, Lord Chelmsford rallies the arriving forces into a relief column. Should they fail to break through to Eshowe and relieve the garrison, Colonel Pearson and another thousand British soldiers will suffer the same fate as the poor souls whose bodies still lie unburied along the slopes of Isandlwana.
