According to Susan Samples, the Nazis went to great lengths to conceal their sterilization and abortion program in the Rhineland. Hans Massaquoi describes his experience as a half-African in Hamburg, unaware of the Rhineland sterilizations until long after the war. Samples also points to the paradoxical fact that African-Germans actually had a better chance of surviving the war than the average German. They were excluded from military activity because of their non-Aryan status, but were not considered a threat and so were unlikely to be incarcerated. Samples and Massaquoi also note that African-Germans were not subjected to the segregation they would have experienced in the United States, nor excluded from facilities such as expensive hotels. However, they both state that downed black American pilots were more likely to become victims of violence and murder from German citizens than white pilots.
