The English historian Sir Harry Hinsley, who worked at Bletchley Park, similarly assessed it as having "shortened the war by not less than two years and probably by four years".
Anglický historik Sir Harry Hinsley, ktorý pracoval v Bletchley Park, vyjadruje podobný názor o: skráteniu vojny prinajmenšom o dva roky, a pravdepodobne dokonca o štyri.
