Continuing on a theme this medal shows the extended view of the trench system and the barbed wire forward of the trenches being laid. One soldier is hammering in wire support posts whilst a second one is pulling the wire tight. Even the coil of wire he's using can be seen to the right.
Below soldiers bring in still more supports and some are laying the sand bags along the trench parapet
Bronze 82 mm dated 1915
