A 35-pound howitzer shell and an 18-pounder shrapnel, such as that fired by the British field artillery, were sent on their mission of death from guns of practically the same weight. Thus greatly did an increase in muzzle velocity mean a corresponding increase in avoirdupois.
Thirty-eight hundredweight was generally agreed by gun-experts the world over to be the weight permissible for field pieces; this limit being imposed by questions of mobility and transport.
It was to gain those assets so great to the French military mind, low trajectory and high muzzle velocity, that the weight of the "75" shell was dropped to 15 pounds.
Howitzer against field-gun, with high explosive shell for both, was German practice against French practice. As one who became very tired of the continuous rain of big German howitzer shells, I must confess a wholesome respect for Hun theory in relation to questions of modern artillery. But no German gun, light or heavy, could, to my mind, compare with the wonderful "75."
A return to General Putz's headquarters found the French staff in possession of a report from the Front, to the effect that the Algerian Brigade had taken Lizerne, held all the trenches on the west side of the canal, and were preparing to cross the canal at Lizerne and Het-Sas.
Later developments showed the French officers in the fighting line had again been optimistic to a point of inaccuracy in reporting Lizerne captured. The next day it was discovered that the Germans still held two houses on the western edge of canal, and had "dug themselves in" in an entrenched bridge-head on the canal bank. The French troops were in a semicircle, 300 yards distant, and were bringing up, under cover of the night, "75's" on either side of the miniature German fort, and preparing to batter it down by high-explosive shells fired at point-blank range.
The 1st Cavalry Division left the reserve line before Lizerne was finally wholly clear of Germans.
All day the din of battle on the long front had been maddening. Ear-drums became tuned to it for a time. But periods of acute sensitiveness would recur, in which the sound seemed to beat against one's brain with a dull ache, punctuated with sharp pain from the constant concussion.
An evening message from 5th Corps Headquarters told of the failure of the great attack at 2 p.m., owing to gas fumes from the German trenches. A later attack had been organised, in which the Northumbrian Territorial Division had won from the enemy some trenches south-west of St. Julien, and then pushed on and captured St. Julien itself. The Manchesters, too, had taken some German trenches east of St. Julien.
