Hi Bernard,
I have Major-General Ian Lyall Grant's account of the Tiddim Road battles ("Burma: The Turning Point"), to hand, so I will go through it again, and see what may be pertinent to your enquiry. Give me a few days, please.
That was quick, but there is not sufficient detail in Lyall Grant, as he avoids for the most part, reference to General Stilwell's Sino-American force which operated in Northern Burma. Covers all of three paragraphs. Sorry, I thought it may have helped, but not so.
Regards,
Marcus
