Douglas Haig

Haig commanded the First Army at the Battle of Neuve Chapelle. This was the first major British offensive of 1915. The attack achieved a limited breakthrough but failed to exploit it due to communication and supply problems, foreshadowing later trench warfare difficulties.

Haig commanded the British Expeditionary Force during the Battle of the Somme. The offensive resulted in over 400,000 British casualties for minimal territorial gains. The first day, 1 July 1916, saw 57,470 British casualties, the bloodiest day in British military history.

Haig launched the Third Battle of Ypres in Flanders. The offensive aimed to break through German lines and capture the Belgian coast. After months of fighting in mud, the Allies gained about five miles at a cost of over 300,000 casualties, with no strategic breakthrough achieved.

Haig commanded the British forces during the final Allied offensive that broke the German army. Beginning with the Battle of Amiens on 8 August 1918, the offensive pushed the Germans back continuously until the Armistice on 11 November 1918, ending World War I.
