What are you working on then?
I believe your info is wrong. There was Maaten Gerawala, it was SE (!) of Mersa Matruh, and there is no way it was occupied by the Germans in August 1941. I believe it was either LG 09 or LG 10.

On a more general note, there were no major operations I am aware of in August 1941 that would have led to the occupation of an LG.
All the best
