PLATE LXXXIII.
THE ST. QUENTIN CANAL.
The canal cutting looking down from above the tunnel mouth—an "absolutely impregnable" portion of the Hindenburg Line defences.
PLATE LXXXIV.
THE RIQUEVAL BRIDGE.
The only bridge over the St. Quentin Canal which was not destroyed by the Germans before our attack on their "impregnable" position in September, 1918. A small party of the Midland Territorials, under Captain Charlton, reached it in the fog just in time to deal with the sentries, throw the charges into the water, and so save the bridge.
