I/Stukageschwader 77 in may 1940

Hello guys
Is somebody can confirm I/Stg77 on Mertzbruck base between 12 and 16 may 1940? Was this Stg really involved in operations over Namur area like heavy bombing of artillery french colums in the vicinity of Profondeville/Lesves?
Many thanks for your replies

I live a couple of miles away from the Merzbrück airfield, the first group of Stuka-Geschwader 77 was indeed deployed there from May 11-16, 1940.
