outskirts of Ablain advanced to the refinery along the stream, as the troops at the communication trench reorganised and attacked again. The Germans were forced back and by the evening of 1 June the position was connected with Ablain by communication trenches (fighting in the area continued sporadically from June–September). From 25 to 28 May French attacks towards Andres failed. D'Urbal continued the limited-objective attacks but transferred the main artillery effort south to Neuville. A three-day preparatory bombardment began on 2 June and on 6 June French infantry captured the main road through the village, as the German garrison replied with massed small-arms fire from cellars and demolished houses. German artillery-fire also caused many French casualties but by 11 June, the French had advanced on a front. British First Army The British adopted siege warfare tactics of limited attacks prepared by a greater weight of artillery fire, to capture more ground and hold it with fewer casualties. British attacks resumed near Festubert from Port Arthur north to Rue du Bois, with a night attack by three divisions at on 15 May, after a three-day bombardment, with carefully observed on a front. The German breastwork was destroyed but many of the machine-gun posts underneath survived, as did infantry dugouts under the second line of breastworks. The attack was limited to an objective about forward along La Quinque Rue road. On the right flank the advance succeeded, a silent advance surprising the surviving Germans in the remains of the breastwork and then capturing the (support trench) before digging in. On the left German return fire stopped the advance in no man's land. An attack at on the right by the 7th Division was successful in parts but with many casualties. Much of the German front line was destroyed and captured but scattered German parties in shell-holes blocked both flanks and prevented a further British advance. On 16 May Haig resumed the offensive with the Battle of Festubert, which was fought on the right flank of the Aubers Ridge battlefield, where British troops were ordered to press on to local objectives only after consolidating. By the morning of 17 May, the German 14th Division was forced to retire to a new breastwork dug behind the original front position, connecting the (strongpoint line) behind the front line, with the result that British bombardments and attacks met only small parties of rearguards.
