The first sign of success for the strenuous German efforts upon October 30 was the driving in of Kavanagh's 7th Guards' Cavalry Brigade from their trenches at the Zandvoorde Ridge. On this ridge, {263} which is not more than a hundred and twenty feet high, the Germans concentrated so tremendous and accurate a fire that the trenches were in many places demolished and became entirely untenable. The survivors of the Life Guards and Blues who made up this brigade withdrew steadily through the reserve trenches, which were held by the 6th cavalry Brigade, and reformed at Klein Zillebeke in the rear. Two squadrons, however, and Lord Worsley's machine-gun section were killed or taken by the assailants. The unoccupied trenches were seized by the Sixth Bavarian Reserve Division, who advanced rapidly in order to improve their advantage, while their artillery began to pound the reserves. The cavalry had been strengthened, however, by the Greys and 3rd Hussars upon the left, while the 4th Hussars lined up on the right, and C, I, and K Horse Artillery batteries vigorously supported. In spite of great pressure, the position was held. Farther south the First Cavalry Division was also at very close grips with the Twenty-sixth Division of the Thirteenth German Army Corps, and was hard put to it to hold its own. Along the whole cavalry position there was extreme strain. A squadron of the 1st Royals were forced to evacuate the chateau of Holebeke, and the line in this quarter was pushed back as far as St. Eloi, thus flattening a considerable salient. The danger of a position which consists of so long a line with few reserves is that any retirement at any point immediately exposes the flanks of the neighbouring units to right and left. Thus the evacuation of Zandvoorde threw open the right flank of the Seventh Division, even as its left had been in the air upon the day before. On getting through, the Germans were {264} on the right rear of the 1st Welsh Fusiliers and enfiladed them badly, destroying all the officers and a considerable proportion of the regiment, which had already been greatly reduced. Colonel Cadogan was among those who fell. The 22nd Brigade was forced to fall back, and the 2nd Yorkshires and 2nd Scots Fusiliers, of the 21st Brigade, being left in a salient, suffered heavily, especially the latter battalion, the conduct of which from first to last was remarkable even among such men as fought beside them. These two regiments held on with the greatest determination until orders to retire reached them, which were somewhat belated, as several orderlies were killed in bringing them. The 2nd Bedfords, who had themselves sustained very severe losses from the German artillery fire, covered the retirement of the remains of these two gallant units. The Seventh Division then covered the line from the canal through Klein Zillebeke and along the front of the woods to near Gheluvelt.
