This thesis aims to explore and unravel the importance of the Ardennes Offensive - often referred to as the Battle of the Bulge - in the history of World War Two and the Post-War world. The study will focus on how and why the engagement between the Allies and the Wehrmacht was so crucial and what makes it be placed among other tide-turning battles such as Stalingrad, Kursk, Midway, or Guadalcanal. For the aforementioned goals, the thesis provides a thorough examination from the Allied D-Day landings, all the way to the breaking of the Siegfried Line, including war aims, plans and an analysis of the Bulge Battle itself, even touching upon the war's end.
