Photographic Sources
28-56: Johannes Haehle's photos
57: German soldiers with clothing, 29.9.41, from BY massacre, different photograher - ЦДКФФАУ, од. зб. 0-11410.
58. German soldiers sorting clothing,29.9.41, from BY massacre, closer to ravine, different photographer - ЦДКФФАУ, од. зб. 0-11411.
I doubt the above is complete, because I've not bothered to look up the sources cited in 2 journal articles on the BY massacre and Wehrmacht complicity.
It doesn't include the hundreds of witness testimonies gathered in about a dozen West German investigations into Sonderkommando 4a, Pol.Btl 45, Pol.Btl. 303, and Sonderkommando 1005, and in at least five Soviet investigations (post-liberation, Kiev trial in 1945, a 1950 investigation, a 1960s one, and one in 1980).
Nor does it include the fact that news of the massacre leaked to the outside world within 2 months. But let's add a few of those, since these reports leaked in multiple directions and cannot be traced back to a single source.
Contemporary Newspaper Reports
59. Krakiwski Wisti, Ukrainian collaborator paper in Cracow, reported by Jewish Telegraphic Agency on 21 October 1941 (dateline London 20 October 1941) saying that the Jews had been driven out of Kiev, 'the last Jew was expelled from Kiev on September 29'.
60. Fred Oechsner, United Press Bureau chief in Berlin, New York Herald Tribune article of 29 October 1941, reporting German sources about liquidations of Jews in Kiev, Zhitomir, Cherson, also noting that 'the Ukrainians took care of matters'.
60a. Neue Zuercher Zeitung, 30 October 1941, 'Eindruecke aus Odessa', reprint of report of United Press correspondent travelling over Ukraine: 'Im Laufe unserer Reise hoerten wir oft von deutschen und rumaenischer Seite von summarischer Behandlung der Juden in Kiew, Shitomir, Cherson und anderen Orten, und die Deutschen erzaehlten haeufig, dass die Ukrainer selber die Sache in die Hand genommen haetten'.
61. Felice Bellotti, “Le mine ‘assassine’ di Kiev,” La Stampa (Turin), October 31, 1941, p. 3 - Italian journalist visiting Kiev in October 1941 on the same tour, told by city administration that all the Jews had gone, and wondered where. See here for more. The 30 journalists taken to Kiev also asked Hauptmann Koch about the massacre, see document 9 listed above.
61a. By contrast, the remarks by the city administration were not mentioned in Alex Small, “Ruins of 5 Day Blaze – Kiev’s War Reminder,” Chicago Daily Tribune, October 23, 1941, p. 1.
62. Jewish Telegraphic Agency report of 16 November 1941 about massacre of 52,000 Jews in Kiev
62a. Pravda and Izvestiia, 19 November 1941, reporting massacre of 52,000 Jews in Kiev, repeated in Pravda, 29 November 1941. Counted as same root source - JTA correspondent probably learned the information from same informant in Kuibyshev/Moscow, but was able to publish.
63. JTA report of Russian eyewitness who had escaped across Soviet lines, confirming massacre, 28 August 1942.
