[5] Possession of Caen and its surroundings would give Second Army jumping-off points to attack southwards and capture Falaise, which would in turn act as a pivot for a swing right to advance on Argentan and then the Touques River.[9][10] In an effort to force the Panzer-Lehr to withdraw or surrender, and to keep operations fluid, the British 7th Armoured Division pushed through a recently created gap in the German front line to capture the town of Villers-Bocage.[15] On 26 June the British launched Operation Epsom, an attempt by Lieutenant-General Richard O'Connor's VIII Corps to outflank Caen's defenses by crossing the River Odon to the west of the city then circling eastward.[22] German forces still held part of the city on the southern side of the Orne river, including the Colombelles steel works, a vantage point for artillery observers.[26] Montgomery approved Operation Cobra,[27] a major break out attempt to be launched by the First Army on 18 July, and ordered Dempsey to "go on hitting: drawing the German strength, especially the armour, onto yourself - so as to ease the way for Brad[ley]".On the morning of 18 July, with heavy air support, advance elements of the 3rd Canadian Infantry Division were able to capture Colombelles and Faubourg-de-Vaucelles, a series of industrial suburbs just south of Caen along the Orne River.[38] Units of the Queen's Own Cameron Highlanders of Canada, supporting the South Saskatchewan Regiment of the 2nd Division, were able to secure a position in St. André-sur-Orne in the early hours of 20 July but were soon pinned down by German infantry and tanks.[40] A simultaneous direct attack up the slopes of Verrières Ridge by the South Saskatchewans fell apart as heavy rain prevented air support and turned the ground to muck, making it difficult for tanks to maneuver.[41] Caen south of the Orne was captured, but the failure to seize Verrières Ridge led Montgomery to issue orders on 22 July for another offensive, this time to be a "holding attack", within a few days, in conjunction with Operation Cobra.
