The story of Private E H (Garry "Snowy") Roselt who served with the 2/15 Australian Infantry Battalion from June 1940 until he was killed in action during an offensive patrol on 31 August 1941. The author was Snowy's daughter Marge, who wrote the book mainly from details recorded his diary and the recollections of ten 2/15th Battalion close mates - all Rats of Tobruk.
