In late April, the
11th Brigade (Brigadier General
James Cannan), which held the line south of the 10th Brigade, was relieved. Their replacements were the
9th Brigade (Brigadier General
Charles Rosenthal). This brigade had been detached from the 3rd Division earlier and had taken part in the fighting during the
First Battle of Villers-Bretonneux. Due to heavy casualties, the 9th Brigade had been reduced to three battalions:
33rd,
34th and
35th Battalions. Its fourth battalion, the
36th had been disbanded to provide reinforcements to the other battalions in the brigade. It had been given two weeks' rest before being rotated into the line, where they assumed a position between the 10th Brigade on their left and the 5th Division's
8th Brigade on their right. On 29 April, while touring the front, it had become apparent to Rosenthal that his brigade's outpost positions on his right were isolated and vulnerable due to a series of sunken roads, vegetation and other terrain features that provide cover for a German surprise attack. Rosenthal decided it was necessary to push his line forward across the valley to the next slope. The 34th Battalion, holding the southern part of the 9th Brigade area, was detailed for the task. They would be supported by the
3rd Pioneers and fatigue parties from the 33rd Battalion, to dig trenches and lay out wire obstacles. The 35th Battalion, holding the northern part of the brigade front, would clear several German positions in front of its line to the protect the flank of the 34th Battalion. Direct fire support was provided by the
10th Machine Gun Company, while the 9th Light Trench Mortar Battery provided indirect fire support. Between 4 and 9 May, the Australians attempted to capture the German front line positions around Morlancourt, which were held mainly by troops from the 237th Reserve Infantry Regiment,
199th Division. Using
peaceful penetration tactics, the Australians launched raids over several nights. The raids proved largely successful, except for an abortive attempt on 7 May, when the late issuing of orders resulted in a hasty and poorly co-ordinated operation that resulted in a company from the 34th Battalion – with reinforcements from the 33rd – being cut off, after having broken into positions held by the German 114th Infantry Regiment. Surrounded on each flank, when daylight came, the company was forced to surrender. The raids succeeded in advancing the Australian line . Casualties during the fighting in the first part of May amounted to 264 killed or wounded for the Australians and at least 170 Germans captured. After the loss of their front line positions, the Germans reinforced their positions around Morlancourt. The 31st Infantry Regiment was detached from the 18th Division and loaned to the 199th Division, moving into the line around the Bray–Corbie Road. The Australians also rotated their forces, with the 2nd Division relieving the 3rd, who had been in the line for almost seven weeks. On 11 May, the area around Morlancourt was assigned to the
5th Brigade, consisting of the
17th,
18th,
19th and
20th Battalions, which had been out of the line resting. As the 2nd Division's
6th Brigade began preparing to capture Ville to the north, the 5th Brigade began sending out patrols opposite Morlancourt, securing several prisoners and machine guns. Throughout 13 May, efforts were made to locate a German outpost opposite the 17th Battalion and at 3:00 am the following day 4.5-inch howitzers from the 107th and 108th Batteries shelled the position. A patrol was then sent out to ascertain the effect of the shelling but it was turned back by heavy machine gun fire, which confirmed that it was still intact. At 3:45 am, the Germans retaliated with a heavy artillery bombardment against the 17th Battalion's positions around the Bray–Corbie Road. Following this, the Germans launched a counter-attack against the 5th Brigade with 200 troops, seeking to regain some of the positions lost to the 34th Battalion during the earlier Australian raids. The attack overran several Australian posts before it was checked and then after a heavy mortar barrage, the three forward Australian companies launched their own counter-attack which subsequently cleared the trenches and released the Australians that had been temporarily taken prisoner. By 10:30 am the fighting had concluded with another 48 soldiers from the German 31st Infantry Regiment being captured. Against this, the Australians had lost a further 60 men killed or wounded. ==Aftermath==
