To figure out if a war story is true, you could look for consistency in details. If different parts of the story contradict each other, it raises doubts. And research similar events to see if this one aligns with common patterns and known circumstances.
You can look for supporting evidence, like historical records or multiple consistent accounts. If there's no solid proof and it sounds too good to be true, it might not be.
Well, one way to tell is by checking the credibility of the source. If the person telling the story has a reputation for honesty and provides details that can be verified, it's more likely to be true. Also, compare it to known facts and see if it fits within the historical context.
