No, you're just wrong. It's not comparing Gallipoli to Gettysburg, or even the western front to Gettysburg. It's comparing Gettysburg to Pea Ridge, and WWI trench warfare to Gallipoli. It's entirely about proportion and history. In the sphere of the American Civil War, Gettysburg is vastly more recognizable than Pea Ridge (which I would have to look up to know anything about, and a fair amount of my high school education referenced the Civil War). Americans were the ones involved in that war, and among them, Gettysburg would stand out.
In the history of WWI, the western front is vastly more recognizable than Gallipoli. More than just Australians and New Zealanders were involved in WWI, so among all the nations involved in WWI, Gallipoli would not be as recognizable.
You're making a mountain out of a molehill. No one is denigrated by that passage. It's a comparative example.
No, you are "just wrong".
Your understanding in no way reflects that of a person living in England, France, Germany, Turkey, New Zealand, Austria, Australia, Italy, or Russia in 1916. No one from Germany, France or England would have said they participated in trench warfare on the western front; they would have fought in the Battle of Ypres, the Battle of Verdun, the Somme Offensive, which were widely reported about in newspapers at home. Its entirely about proportion and history, which the author was completely lacking, when it came to his references beyond the American.
It is only your distance to the historical events in question, which allow you to lump all the battles on the western front during WWI together, and state that as whole, they are more recognizable than a certain specific single event. A statement, which, while obviously true, completely ignores the fact that at the time it occured, this single event was well covered by newspapers in Germany, England, Australia, Canada, New Zealand, precisely because it was of interest to those at home. In other words, it was recognizeable to the people of those cultures, at that time, and for some time thereafter, as evidenced by its commemoration already in 1916, in Australia, New Zealand, and England.
How many other battles have actually been commemorated during wartime? That in and of itself should provide some understanding as to how "recognizeable" the event was to the people of that time.
