Virtually unknown. It’s not just that this broadside is unrecorded on OCLC but we could only find a single published reference to this announcement. That article dates the announcement 22 July, 1941, nearly six weeks after that printed here.
In May, 1941, Henry Maitland Wilson (1881-1964) was placed in command of British Forces in Palestine and Trans-Jordan, including overseeing the Syria-Lebanon campaign which overthrew the occupying Vichy regime. Wary of German (and other) insurgents, Maitland issued this order - which would’ve been posted on walls in Beirut and Damascus and likely accounts for the low survival rate.
The six articles here prohibit the carrying of firearms and other weapons; firing on British troops or people employed by them; ; the destruction of telegraph or telephone wires; stealing or receiving goods stolen from the British or Allied governments; or “commit[ting] any other act of deed inimical to the interests or safety of the British or Allied Troops.”
