Perhaps the most controversial aspect of strategy in World War I was the difference among the British between the "Western" viewpoint (held by Field Marshal Haig) and the "Eastern"; the former being that all effort should be directed against the German Army, the latter that more useful work could be done by attacking Germany's allies. The term "Knocking away the props" was used, perhaps as an unfortunate consequence of the fact that all of Germany's allies lay south of (i.e. 'beneath') her on the map. Apologists and defenders of the Western viewpoint make the valid point that Germany's allies were more than once rescued from disaster or rendered capable of holding their own or making substantial gains by the provision of German troops, arms or military advisers, whereas those allies did not at any time provide a similar function for Germany. That is, it was Germany which was the prop, and her allies (particularly Bulgaria and Austria-Hungary) did not suffer significant reverses until Germany's ability to come to their aid was grossly impaired.
