Basing whether or not Bishop deserves the VC on the warrant controling award of the VC is a valid point, HOWEVER, with missing information on the award of Bishop's VC, we could be missing information that was presented by 3 independent witnesses, as called for in the warrant.
The reason I mention this is that as far as I've been able to determine, the announcement of the award for Bishop's VC took longer than any other awarded to a RFC/RNAS/RAF ace. And most likely, took the longest of any awarded during that war.
But I will only stipulate to the awards to other aces, as they are the only ones to which have pertinent data available here to make that statement.
It is my OPINION, that based on the amount of time, they likely gathered witnesses from some source who confirmed Bishop's attack.
Unfortunately, as pointed out in Markham's article those documents related to the VC award, other than the announcement of the award it's self appear to have been lost or destroyed. Consequently, we'll never know for sure. But I can't, I WON'T believe (until proven 100% otherwise) that the British Empire would suspend the rules for their highest award simply to create a hero.
I have to think that some bureaucrat in the PRO or where-ever decided that Bishop's reputation was beyond reproach and didn't need the corresponding documents to his VC award, thus destroying them to make space for some more deserving soul's records.
And if that isn't good enough, as Barrett said, possession is 10/10th's of the law.
