Even though, only the winning side would draft the “official” version of the events. The “real” “truth” would appear only decades later, when everyone involved is dead (or almost) and independant research can happen. E.g. a former French “résistant” recently confessed his group summarily executed a bunch of captured German Soldier in 1944. Some of the members went in politics afterwards, preventing any investigation to take place.
Sure, as you know that you can throw people overboard to save your own ass.
