 Later, in October 1917, the 43rd took part the Third Battle of Ypres, attacking around Broodseinde at the start of the month and then around a week later.During the fighting around Broodseinde, the 43rd formed part of the 3rd Division's spearhead and was successful in helping them advance over , while during the attack on Passchendaele the battalion formed part of the divisional reserve along with the rest of the 11th Brigade and was committed to the front line late after the assaulting forces were forced to retire after their initial gains were negated by German attacks on the division's flank.In early 1918, after the collapse of Tsarist Russia enabled a significant shift of German combat power from the Eastern Front to the Western Front, the Germans launched their Spring Offensive.
