If by "his escapades" you mean his time in captivity and escape, his records, should you choose to apply for them, will have no more than the dates (which you have already) and perhaps a record of which camp he went to. You have seen his listing on the POW lists which are simply that, there is no detail of the time between.
Presumably he didn't leave an written record with the family? Have you tried local newspapers?
