Luftwaffe and Allied Air Forces Discussion Forum

I’m researching air activities around Noordwijk village. It is situated on the Dutch coast, west of Leiden. During the occupation a heavy battery of the German navy was situated to the north of the village. Every now and then the battery and the village were the target of bombs or machine gunfire. Nothing on a large scale however.
Who can tie this incident to a specific allied aircraft?

July 8/9 1941
At 02.50 several hand grenades are dropped from an aircraft over Noordwijk battery. They explode at 1000 meter height. ????????????????
