No two young men could be closer than Rupert and Edgar Clinton. Two brothers living carefree at school, until a stranger approaches and reveals a secret past. Shocked, Edgar runs away and joins the British Army. He then embarks with his unit to Egypt, on the Nile Expedition, to relieve British forces under siege at Khartoum. These forces, led by Charles Gordon, are being attacked by the forces of a Muslim Mahdi (prophetic leader). Will Edgar and his unit reach Khartoum in time? Will Edgar survive the battle? Will Rupert ever see his brother again? These questions, and more, are answered in Dash to Khartoum: The Nile Expedition by G.A. Henty. Set in late 19th century Africa, this book includes more than one hundred geographical, historical, and explanatory footnotes to aid the modern reader.
