I have found this video of Jews in mandatory Palestine building trenches and fortifications from July 1940. In that specific time period, what were they preparing for?


This is the video in question: https://www.youtube.com/watch?v=TlHET090Ryg
The archive dates this specific video to the 22nd of July 1940, and in the archive it is tagged under “civilian defense” (in Hebrew).


Definitely attacks from the Germans or Italians. I believe it depicts Haganah, a group that would later become Irgun.
