The German attack upon the British lines by the army of General von Quast in Flanders broke on the morning of April 9. There had been considerable shelling on the day before along the whole line, but as the hour approached this concentrated with most extreme violence on the nine-mile stretch from the village of Givenchy in the south to Fleurbaix, which is just south of Armentières in the north. This proved to be the area of the actual attack, and against this front some eight German divisions advanced about 6 o'clock of a misty morning. So shattering had been their bombardment and so active their wire-cutters, who were covered {227} by the fog, that the advanced positions could hardly be said to exist, and they were able to storm their way at once into the main defences. The point upon which this attack fell was held the by four divisions, all of which formed part of Horne's First Army. The general distribution of the troops at that time was that the Second Army stretched from the junction with the Belgians near Houthulst Forest down to the Messines district where it joined the First Army. The First Army had weakened itself by an extension to the south, and Plumer's force was about to extend also, and take over the Laventie district, when the storm suddenly burst upon the very point which was to be changed. Two corps were involved in the attack, the Fifteenth (De Lisle) in the Armentières region, and the Eleventh (Haking) in the region of Givenchy. The latter had two divisions in the line, Jeudwine's Fifty-fifth West Lancashire Territorials defending the village and adjacent lines, while the Portuguese Second Division (Da Costa) covered the sector upon their left. The depleted Fiftieth Division (Jackson) was in immediate reserve. On the left of the Portuguese was Ponsonby's Fortieth Division which had lost five thousand men in the Somme battle only a fortnight before, and now found itself plunged once more into one of the fiercest engagements of the war, where it was exposed again to very heavy losses.
