renewed bombardment was ordered from 06.15 to 07.00, but the artillery's forward observation officers (FOOs) were unable to locate the hidden German machine gun positions, which required a direct hit from an HE shell to be put out of action. The second attack failed as badly as the first, as did two others launched during the afternoon, and the survivors were pinned down in No man's land until nightfall, despite a further bombardment being laid on to allow them to withdraw. Festubert Although 2nd London Division suffered few casualties at Aubers Ridge, its gunners had learned a sobering lesson about the impossibility of suppressing strong defences with inadequate guns and shells. On 11 May the division was redesignated 47th (1/2nd London) Division, and on the night of 14/15 May it took its place in the line for the Battle of Festubert. The guns were already in place, with 47th Divisional Artillery operating under the control of 7th Division. Despite the continuing shortage of ammunition, the plan this time was for a long methodical bombardment. On 13 and 14 May the field artillery carried out three two-hour deliberate bombardments each day, with the howitzers registering the enemy support and communication trenches with observed fire, and then firing to destroy them, along with certain important salients in the front line. Intermittent bombardments were continued during the night to stop supplies being brought up and to prevent repairs being carried out. The guns fired about 100 rounds per day. Unfortunately, the FOOs reported that many of the howitzer shells failed to explode due to faulty manufacture of the fuzes. During 15 May feint bombardments mimicking the moment of assault were carried out, but the actual attack was made after dark with some success. The fighting went on for several days, and between 18 and 20 May the Canadian and 51st (Highland) Divisions took over the line under the command of Lt-Gen Edwin Alderson as 'Alderson's Force', with 1/VIII London Bde among its supporting artillery. 47th (2nd L) Division made its own first attack on the night of 25 May. The leading brigade captured the German front and support trenches, but was then pinned down by accurate German artillery fire and could advance no further. This effectively ended the battle. Loos In June 47th (2nd L) Division took over trenches in front of Loos-en-Gohelle from the French. In August the divisional artillery was rested
