"Jeff" Phipps-Hornby and Frederic Coleman comparing underpinning outside Ypres, May, 1915; the thinnest and thickest "supports" in the 1st Cavalry Division
face p. 261
From the Zonnebeke Road south, across the Ypres-Roulers Railway, as far as the Bellewaarde Lake, troops of the 28th Division composed the firing line.
They joined the left flank of the 18th Hussars, who occupied a position on the south side of the Bellewaarde Lake and in front of the Hooge Château, the trenches at that point being about thirty yards to the east of the château ruins. The right of the 18th Hussars rested on the Menin Road, and close behind them in reserve were three score odd York and Durham Tommies who had been sent up to dig.
South of the Menin Road, in the Sanctuary Wood, came the 9th Lancers, 11th Hussars, Queen's Bays, and 5th Dragoon Guards, respectively.
The 4th Dragoon Guards, 15th Hussars, and 19th Hussars were in reserve in the G.H.Q. line.
The night was less disturbed by gun-fire than usual, and even the rifle fire and itinerant sniping were of less volume than for weeks past.
General de Lisle, noticing the strong westerly breeze die away, and the wind shift to the east during the course of the afternoon, sent a warning to the troops in the trenches to be on the look out for a German gas attack next morning.
