1 August 1943 Guernsey fortifications and tunnel-use map — 1943-08-01

Editorial note: Two copies of the 1 August map are consolidated. The larger named scan is embedded. The translations differ on the final Luftwaffe tunnel number (41 or 47); it remains uncertain and is not used to infer a separate tunnel.

Editorial note: Other copies or associated sheets are cited together; repeated text is counted once.
