570 Sqn 23/09/44 - a/c and Gliders ?

[Alex Smart]

Hello,
From what I have found on line.

On 23/09/44 some 14 a/c of 570 Squadron were tasked with resupplying troops at Arnhem.
It turned out that four a/c were lost( EF298; LJ883; LJ991 and LK191 ). Two others were to make forced landings ( LJ622 and LJ996 ).

Of the original 14, how many were used to tow Gliders this day ? As nothing seems to be noted as far as I can find.

It would seem that if they did it would be Horsa Gliders they towed.
What if anything is known of these Gliders on that day , serial numbers, fate , etc.

AB's serial number books do not show any losses for this date, only 17,18,19 and 22nd are noted with serial numbers as "lost". Nothing for 23/09/44.

So of the 14 Stirling's, if they were tug a/c then what of their 14(?) Gliders ? Were some lost when the four Stirling's went down - had the gliders already been released ? Or when the other two made forced landings, presumably their two Gliders had already been released.
Or perhaps not all 14 were used as tugs ?

Sorry if I drifted but hope my request is reasonably understandable.
Basically seeking Stirling tug-Glider serial numbers links.

Thanks
Alex
