Warsaw Boy is the remarkable true story of a sixteen-year old boy soldier in war-torn Poland' The best-ever account of what is was like to be young and fighting in the Warsaw Rising' Neal Ascherson, Sunday Herald, Books of the YearPoland suffered terribly under the Nazis. By the end of the war six million had been killed: some were innocent civilians - half of them were Jews - but the rest died as a result of a ferocious guerrilla war the Poles had waged.On 1 August 1944 Andrew Borowiec, a fifteen-year-old volunteer in the Resistance, lobbed a grenade through the shattered window of a Warsaw apartment block onto some German soldiers running below. 'I felt I had come of age. I was a soldier and I'd just tried to kill some of our enemies'.The Warsaw Uprising lasted for 63 days: Himmler described it as 'the worst street fighting since Stalingrad'. Yet for the most part the insurgents were poorly equipped local men and teenagers - some of them were even younger than Andrew.Over that summer Andrew faced danger at every moment, both above and below ground as the Poles took to the city's sewers to creep beneath the German lines during lulls in the fierce counterattacks.
