28 September-11 November 1918, the Final Advance in Flanders. The British Second Army and Belgian Army combine and finally break out of the Ypres salient. More ground is gained in a day that in the entire Passchendaele offensive of a year before. The offensive continues through fighting in the Courtrai area and eventually well across the Scheldt.
The map above illustrates the advance of the British Second Army from 28 September (the position being the solid red line at Ypres shown on the left of the map) to 11 November 1918 (the solid red line at Grammont on the right of the map), with phase-lines in between. The red line of crosses was the start position for operations on 14 October. Note how by that date the Allied forces were well clear of Ypres – the attack of 28 September achieved in 24 hours a deeper advance from Ypres than the entire Third Battle (Passchendaele) had achieved in 1917. North of Second Army came the Belgians, and in the latter stages the United States forces in the Audenarde (Oudenaarde) area; south of Second Army was the British Fifth Army.
