The front of Cavan's Fourteenth Corps was formed by the grand old Twenty-ninth Division upon the left, and the Twentieth Light Division, the heroes of many fights, upon the right. Both divisions lived up to their highest that day, which means that many a brave man died at his highest to carry on the record. On the whole, the Mebus or pill-boxes, the new German concrete forts, were less effective in the north than in the south, which may have depended upon the general lie of the country which gave them a shorter area of fire. Small bodies of brave men—sometimes a single brave man—managed to get up to them and to silence them by hurling a sudden bomb through the porthole from which the gun protruded.
The advance of the Twenty-ninth Division was begun by crossing in the early dawn the bridges thrown over the Steenbeek. Starting from the line of the stream, the advanced mud-beplastered lines, extending as they crossed country, coalescing as they concentrated upon any obstacle, moved swiftly forwards to their objectives, which were taken in their entirety. Passerelle Farm was carried by the veterans of the Twenty-ninth, and so was Martin's Mill upon the right, many prisoners being sent to the rear. Another heave took them across the grass-grown lines of the abandoned railway and on into the hamlet of Wijdendrift, the line being established well to the north-east of that place.
Whilst the Twenty-ninth Division had made this fine advance upon the left, the Twentieth had done equally well upon the right, and had ended their brilliant attack by storming after a short but sharp contest the village of Langemarck, that old battle centre of 1914.
The start of the attack was as fine as its execution, for the two brigades were marshalled into their positions in pitch darkness upon ground which was bewildering in its badness, close under the untaken redoubt of Au Bon Gite, whose garrison at any moment might give the alarm. So silent was the operation that the enemy was utterly ignorant of it, though they kept up a continual machine-gun fire all night which made the assemblage even more difficult. In the early dawn the German fort was rushed by two companies of the 11th Rifle Brigade under Captain Slade.
