At 4:45am on the 16th of August, exhausted and weak from previous fighting, the 48th and 49th Irish Brigades launched their attack, with the 47th brigade in reserve. During the previous few days, there were many casualties sustained from shell fire, gas poisoning and sickness - the latter due to very adverse weather conditions, rain having fallen continuously during the previous four days and nights.
The 7th Royal Irish Rifles and the 9th Royal Dublin Fusiliers led the attack, with the 2nd Dublins in support. Some little time before zero hour on the 16th of August, the Germans had opened up a heavy barrage in which the 9th Dublins and 7th Faughs lost approx. 65% of the men in each battalion before they even began their attack. As soon as they attacked, the 48th Brigade was badly cut up by machine gun fire from German machine gun positions at the Potsdam, Vampire and Borry Farms which were in direct line of the advancing Brigade. B Company under Captain Byrne of the 2nd Dublin Fusiliers was practically annihilated, only two officers and three other ranks survived. The attack was carried out on open wet and muddy ground. A message had come back to the 2nd Dublins headquarters at Frezenberg Redoubt that the German machine gun post at Vampire Farm contained five machine guns. At 9:30 am, C Company of the 2nd Dublin Fusiliers, in accordance with orders from the Brigade, moved up in support of the 9th Dublin Fusiliers who had suffered severely from intense machine gun fire and succeeded in getting to within one hundred yards of Bit Work which was their objective. Only two officers and ten men remained, the rest of the battalion were either killed or wounded. This was the end of the 9th Dublin Fusiliers.
On the 17th of August, the 48th Brigade moved back to their camp at Vlamertinghe. The 1st, 2nd, 8th and 9th Battalions of the Dublin Fusiliers, along with the 7th Battalion of the Royal Irish Fusiliers, lost eighty two officers and 1,550 men of other ranks.
