World War I ought to be seen as an object lesson on the perils of fighting a 20th century war with 20th century weapons using 19th century military strategies. Curry successfully brought new tactics and extensive training to bear on the intractable situation of trench warfare in 1917 - for that alone he should be remembered, yet the history I was taught growing up in the 1960s and early 1970s did not mention him. Nor was I aware that part of the reason for this absence was due to the disapproval of Mackenzie King, as gleaned from the comments.
One of the comments took offense at the glee in which a soldier described "mowing down" the enemy. The comment was made from the temporal superiority with which a person of our time regards the actions and attitudes of the past as barbaric, implying that society has since moved on to become more enlightened. "Modern" society is no less bloodthirsty than its predecessors, nor less reticent to tar all members of a certain group with the same brush.
