Help Please Torpedo Boat Attack

[Peter Harvey]

Hi,

Your help would be appreciated please. I have attached a nice German card showing a Torpedo Boat attack, no details of where but cancelled with the cachet 4 Kompagnie V11 Matt Artl Abtlg, I assume this is a shore artillery unit, potentially a harbour defence.

The card message is in German top left I can not read (potential location) then date 16/8 1915.

Any help would be appreciated.

Peter
