It is not an exact match, but the closest I found: Frontal pass in WW2-era air combat.
Sometimes, during a fight, pilots went separated from the other fighters and started a one-to-one fight. It was especially true at the beginning of WW2 and during WW1, when group tactics were not widely used.
Sometimes, one of the airplane in a duel could come out of ammunition or fuel. Of course he could flee out of ammunition, but low on fuel, if he flees he could be caught up by the other fighter. So he tried to engage in a frontal pass the other plane.
It is not very clear whether the action was "accepted" by the other pilot, or if the other pilot should be forced to engage the frontal pass. But in the end, it did consist in:
So in this example, pilot don't borrow ammunition to the other, but he did ask to end the fight on a "glorious knight duel" rather than "I am short of ammunition".
