Britain had slowly, and begrudgingly, rearmed in the 1930s only after Hitler had appeared has a clear threat. Her dominions pledged their assistance to England and her allies, but not all declared war on September 3, 1939. Canada waited until September 9th to convene her Parliament, and declared war on September 10.
