Tenth book in the Discovering Canada series. Some claim that "nothing is solved by fighting." Others say, "stand up and fight for your rights" when you are threatened or intimidated. Fighting should be the last resort, used only when every peaceful effort has been exhausted. The Great War (1914-1918) inspired courageous heroes and established a proud Canadian nationalism, but it was a devastating, horrific bloodbath that killed or maimed almost half of Canada's brave soldiers in deadly battles such as Ypres, the Somme, Vimy Ridge, and the final 100 days. Young readers will discover Canada's part in the first great worldwide conflict. They will learn about life in the trenches, the first tanks, U-boats and convoys, aces and dog fights, machine guns and cavalry charges, gas warfare, as well as the drastic changes in women's roles. Hands on activities include creating a multicultural force, writing a coded message, targeting and observation, and much more. Sales of the first eight books have topped more than 100,000 copies.
