It grew enormously in strength two years later when, lazing in the summer on the banks ofthe school close, with the scent of new-mown grass in the air, I read for the first time an account ofthe British retreat to Dunkirk. How could a British army have come to find itselfin so near-disastrous a position? How could things have been allowed to go so far? My need to understand drove me to wangle, connive, volunteer and out-compete my fellow conscripts to a posting to British Troops, Austria as an acting sergeant in Field Security, concerned with the tail-end of denazification, with keeping an eye on the wilder and madderedges ofthepolitical spectrum, firstly among theinhabitants of Styria, thenamong thetidesofrefugees fromsouth-easternEuropethat thepolitical processes from 1943 onwards werewashing westwards out ofRomania, Hungary, Yugoslavia, Czechoslovakia and the Ukraine. I learntalmostimmediately thattherealities ofCentral European politics covered a very widerangeofattitudes, virtuous andvicious, unimagin- able to a teenage schoolboy in anisolated andblockaded island between his eleventh and seventeenth birthdays. The Social Democratic political policeman who regarded the neo- Nazis, whose first underground stirrings became known in the winter of 1947, as the rankest ofamateurs; the veteran oftheJewish brigade who, from sheer need to know, kept tabs on the revival of Catholic anti-semitism; the Hungarian Anglophile and liberal Count who first gave me a rough guide to the political differences between the refugees of 1943, 1944, 1945 and 1946 in preparation for the flood of 1947; the broken disciple of Macek, the Croat leader, who for shame at the excesses committed in Croatia's name by Anton Pavelic and his IX HOW WAR CAME followers, only admitted to being a Croat himself in his blackest moments; the Catholic anti-Nazi lawyer; the village gendarme who regarded all politicians as equally dire acts ofGod; the ultra-nationalist doctor (his family came from the South Tyrol), an ex-Reichswehr surgeon, who overcame his Anglophobia to dress my poisoned toe: all of these increased my desire to understand, while at the same time increasing my awareness ofthe complexities to be understood. Few, if any ofthem, fitted the stereotypes ofmy imagining. From the army, my desire to understand drove me to read Politics, Philosophy and Economics, taking the international history of the inter-war years as my special subject. (Historyin Oxford ended then in 1914. In the twenty-five years since my father had emerged from uniform at the end ofa previous world war to read first Classics and then History, the terminal date had advanced from 1870, some thirty- four years. But, apart from a special paper on the Anglo-French Entente, there was nothing for the would-be historian ofthe twentieth century.) I had the good fortune to sit at the feet ofa generation whose historical interests had been developed by service, often at Bletchley Park, or in SOE. Christopher Seton-Watson, my tutor, guided my reading. Finally, with the aidofjohnWheeler-Bennett, I left Oxford to join the small British editorial team working alongside equally small American and French teams to screen and edit for publication the captured archives ofthe German Foreign Ministry. Here I worked in parallel, the first historian to read the Foreign Ministry files for the period 1933-7 (later to be published as Series C of Documentson German Foreign Policy) whileatthe sametimedevilling for theeditors-in-chiefonvolumesV-XofSeries D, especiallyonvolumes VI and VII which ran from March to September 1939. I helped collate thedocuments withthosealreadypublishedin Series IIIofDocumentson British Foreign Policy and with the Italian series published by Mario Toscano, thenthedoyenofEuropeanhistorians ofdiplomacy. I drafted editorial notes incorporating evidence cited in the Tokyo war crimes trials. From working alongside my French and American colleagues I discoveredhow grosslyinadequateintechnicaltermswas theeducation ofwhich I was so proud; and all the time my understanding grew of howfragmentaryinevidentialterms, andhowunsatisfactoryinhuman terms was the accepted orthodoxy of the time. The son ofa school- master, a great, ifself-effacing teacher, I found the language employed to comment upon the motives and comprehensions underlying British policyreminiscentofan end-of-term report.
