premise: Friedrich Wilhelm Konrad von Brodowski, known at "Fritz", (November 26, 1886 – October 28, 1944) was a German army general, controversially killed while in French custody during World War II. His death led to the murder, by way of a reprisal, of an imprisoned French army general, Gustave Mesny.
hypothesis: A new army general got promoted
reason: If one army general dies a new one could take his place, but not necessarily because they may just divide the responsibilities among those of lesser rank
