The Canadian offensive at Vimy Ridge is shown here, as well as the advance across the Douai Plain and the battles of Arleux and Fresnoy in late April and early May. The blue lines mark the progress of the advance and the dates Allied forces reached them. Pink lines mark divisional boundaries. Green lines illustrate old advances.
