text: At 04:45 on 23 April, following two days of poor visibility and freezing weather, British troops of the Third Army (VI and VII corps), attacked to the east along an approximate  front from Croisilles to Gavrelle, on both sides of the Scarpe. The 51st (Highland) Division attacked on the northern side in determined fighting on the western outskirts of Roeux Wood and the chemical works. On their left, the 37th Division, attacked the buildings west of Roeux Station and gained the line of their objectives on the western slopes of Greenland Hill, north of the railway. On the left of the main British attack, the 63rd (Royal Naval) Division made rapid progress against Gavrelle and secured the village. To the south of the Scarpe and east of Monchy-le-Preux the 29th Division gained the western slopes of the rising ground known as Infantry Hill. The Cojeul river marked a divisional boundary within the VI Corps. Guémappe on the north side of the river was the objective of the 15th (Scottish) Division, attacking east from Wancourt towards Vis-en-Artois. The objective was commanded by the higher ground on the south bank and it was not until the 50th (Northumbrian) Division captured the rise on the south side of the Cojeul that the village was taken. Several determined German counter-attacks were made and by the morning of 24 April, the British held Guémappe, Gavrelle and the high ground overlooking Fontaine-lès-Croisilles and Cherisy; the fighting around Roeux was indecisive.
