Major Peter James Cottrell (born 1964 in RAF West Raynham, Norfolk, UK). Anglo-Welsh soldier, sailor, writer, educator and revisionist military historian of the Irish War of Independence and Irish Civil War.
Cottrell is the author of the best-selling military history 'The Anglo-Irish War: The Troubles 1913-23' which challenges traditional nationalist interpretations of the Easter Rising; the role of the Royal Irish Constabulary and the popularity of the IRA campaign whilst supporting the view that the conflict was as much an Irish civil war as a struggle for independence from the UK.
