You're welcome Brian.
It's a strange day as my two searches so far today have each led to the discovery of a friendly fire incident with only a very small connection to the subject of my search.
Here is the second: on 6 April 1944, retreating British and Indian troops near Imphal were attacked by Allied aircraft, suffering casualties (at the end of the page, it is not possible to copy text)
