There was a short story (I think by Alfred Bester) with this premise. I can't find it at the moment though.

[edit]

I found it; it's called Disappearing Act[1]

In a future state of total war, patients at a facility for those with severe PTSD are going missing. They finally discover they are just disappearing while sleeping. Interviewing them, they find out they have been time-traveling to the past to escape the war. The general calls up a number of experts in various fields of sciences to try to understand it, until someone suggests calling in a historian. They find the one historian remaining in the country in a prison for refusing to fight. He observes that the stories reported by the soldiers are ahistorical and likely are fantasies created by the soldiers. He then states that a poet is the only one who could understand this. He then laughs as the general searches the country in vain for a poet.
