"Written by victors" is not really accurate, but there is bias in who it was written by (not least, for most of history, the fact that it is somewhat tautologically written by the literate). Historians are well aware of this and will generally try to account for it by looking to corroborate accounts, but of course it's very easy to project one's own biases onto any such analysis, especially when evidence is thin.
