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.

Philip Jowett's 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). He is married and lives in Lincolnshire.
