It's early 1918 and the Germans have launched a 'shock and awe' offensive, advancing 60KM in only three days. This onslaught triggers a leadership crisis. The Allies realize they must perfect a new way of waging war to deliver ultimate victory. As this dramatic history documentary illustrates, this different approach would completely change WWI, and the way future wars were fought.

In the final months of the First World War, an Allied victory was far from certain. The Germans had their famous Hindenburg Line, the most formidable defensive system in military history. As this compelling history documentary reveals, the combined might of the Allies using artillery, tanks, aircraft and troops in careful concert, eventually turned the tide of World War I.
