Philip Jowett was born in Leeds in 1961, and has been interested in military history for as long as he can remember. His first Osprey book was the ground-breaking Men-at-Arms 306: Chinese Civil War Armies 1911-49; he has since published the three-part sequence The Italian Army 1940-45 (Men-at-Arms 340, 349 and 353). A rugby league enthusiast and amateur genealogist, he is married and lives in Lincolnshire.

Raffaele Ruggeri was born in Bologna where he works and lives with his wife. After studying at the Fine Arts Academy he worked in several areas of graphics and design before deciding to devote himself to illustration. He has long been interested in military history and has illustrated a number of books for Osprey.

With decades of research to draw from Philip Jowett explores this extraordinary David-and-Goliath conflict, where the rag-tag Igbo tribal army of secessionist Biafra faced off against the Nigerian Federal forces. It was an African war that captured the attention of the western media, with individual commanders such as Biafran leader Colonel Ojukwu and Federal Colonel Adekunle becoming familiar figures across the globe. The Nigerian forces easily outnumbered their opponents and benefitted from British and Soviet equipment, yet against all the odds the Biafrans held out for two and a half years, inflicting many setbacks on the Federal forces before their eventual surrender in 1970.

Specially commissioned artwork and historical photos, including some from respected Italian war photographer Romano Ganoni, reflect the diverse array of uniforms and equipment on both sides, with images ranging from Sandhurst-educated officers in immaculate uniform to ragged militiamen armed with World War II kit.
