The German advance on April 9th between Armentières and the La Bassée Canal had bulged in the line by that evening to a distance of three to five miles. Next day, the attack was extended North of Armentières to Wytschaete and Hollebeke, and the enemy gains were extended. The 34th Division in Armentières, though not yet attacked on their own front, had their two flanks dangerously exposed, and were withdrawn in a North-westerly direction, reaching a stopping-place at Nieppe. If we follow this action a little further, we shall be able to fit in more intelligibly the narrative of the 49th Division. On April 11th the advance was pressed in the direction of Nieppe and Neuve Église, and in the afternoon there was fierce fighting about Messines, now in enemy occupation. These losses pinched the 34th out of their temporary foothold at Nieppe. The withdrawal on this day did not cease in that particular area till about a thousand yards East of Neuve Église and Wulverghem, involving the abandonment of Hill 63. Next day, an assault in great strength was launched due westwards between Merville and Steenwerk, and affected our line below Bailleul, which looks down through Nieppe to Armentières. On the same day and the following (the 13th) Neuve Église was hotly involved, and fell before midnight on the 14th. Another twenty-four hours and Bailleul had suffered the same fate. There was now a very perilous salient in this stricken northerly region, and on the night of April 15th/16th the decision was taken to withdraw from the Passchendaele Ridge, the scene of so much bloodshed in the previous summer; and, consequently, to close in nearer to Ypres. These retirements, as may be seen on a map, brought the Kemmel sector into prominence, and the German capture on April 16th of Meteren and Wytschaete, at the two extremes of that front, was developed next morning (17th) into a determined attack on Kemmel Hill.
