This photo was taken in May 1945, in West-Terschelling village, a/d. Boonstra-Oepkes, living in Leeuwarden in those years, Goudsbloemstraat 32.
Apart from the policeman the most likely non-flyer in that group should be the man with spectacles (pilots had to have exceptional eye-sight) the British Army Captain whose name from that signature is difficult to de-cipher...
It could be an enemy defence line, with some watchful soldiers on top, looking out into their direction of course..?

The next year, in 1667, the Dutch under command of De Ruyter executed a retaliatory expedition, and dealt the English navy a heavy blow at the Raid on the Medway (also known as the Battle of Chatham), in effect ending the Second Anglo-Dutch War.
The Raid on the Medway, was a successful Dutch attack on the largest English naval ships, laid up in the dockyards of their main naval base Chatham, that took place in June 1667 during the Second Anglo-Dutch War.
