<entity_0> was the final attack conducted by Canadian and Polish troops, supported by a British tank brigade, during the <entity_1> during World War II. The operation was to capture the tactically important <entity_5> town of <entity_4> and then the smaller towns of Trun and Chambois. Despite a slow start and limited gains north of <entity_4>, novel tactics by the 1st Polish Armoured Division during the drive for Chambois enabled the <entity_4> Gap to be partially closed by 19 <entity_2>, trapping about 150,000 German soldiers in the <entity_4> Pocket. On <entity_2>, elements of the First Canadian Army relieved the Polish survivors and sealed the <entity_4> Pocket by linking up with the Third US Army. Field Marshal Bernard Montgomery hoped that Canadian forces would achieve control of <entity_4> by midnight on <entity_3>. <entity_0> began at 12:00 on <entity_3>, when 800 Avro Lancaster and Handley Page Halifax heavy bombers of RAF Bomber Command struck German positions along the front. Although the first day's progress was slower than expected, <entity_0> resumed on 15 August; both armoured divisions pushed southeast toward <entity_4>. By the evening of <entity_2>, the vast majority of the German forces remaining in the <entity_4> Pocket had surrendered. German casualties during <entity_0> are also uncertain; approximate figures can be found for casualties within the <entity_4> Pocket but not for the Canadian operations during Tractable. In the British and Commonwealth system of battle honours, participation in <entity_0> (included as part of the honour <entity_4> for service from 7 to 22 August) was recognized in 1957, 1958, and 1959 by the award of the battle honours Laison (or "The Laison" for Canadian units), for service from 14 to 17 August, Chambois from 18 to 22 August and St Lambert-sur-Dives from 19 to 22 August.
