system of trenches has been captured on a front of 3,200 yards, and of
the remaining portion the first and second lines of trenches are in
our possession.

The total number of prisoners taken is 8 officers and 777 of other
ranks. Ten machine guns in all have fallen into our possession, as
well as a considerable quantity of material and equipment, particulars
of which are not yet available.

GERMAN GAS WARFARE AGAIN.

_Under date of May 28, an Eyewitness with the British Headquarters in
France continues and supplements his narrative as follows:_

Monday, May 24, witnessed a fresh development in the situation in our
front. It was a most brilliant May day, the heat of the sun being
tempered by a light breeze, which had blown from the northeast during
the night, and in the course of the morning had veered round toward
the north. This breeze gave the enemy the opportunity they awaited of
repeating their gas tactics against our position in front of Ypres,
which, though reduced in prominence, was still a salient in the
general line.

Between 2 and 3 o'clock in the morning a violent bombardment with gas
shells was started against a section of our line about two and
three-quarters miles long, and divided into four approximately equal
parts by the roads from Ypres to St. Julien and Moorslede and the
railway from Ypres to Roulers. The supply of gas available must have
been great, for it continued to pour southwestward for some hours in
great volume, in some places reaching to a height of several feet.
Owing to the direction of the wind, also, it swept southward along our
line as well as penetrating behind it.

The manner in which such an attack develops with a favoring wind
cannot better be described than by the reports of its progress brought
in on Monday morning by our aerial reconnaissances. One observer who
crossed the opposing front in this quarter shortly after dawn reported
when he came back that a thick cloud of what looked like smoke
outlined the whole of the German trenches. The next observing officer,
who arrived some time afterward, stated that to the west and southwest
of the German line he could see a broad band of yellow grass and trees
which looked as if they had been bleached. A third, who came in later,
stated that the whole area behind our line was covered by a mist so
thick as to interfere with observation.

This attempt to asphyxiate was of course preliminary to an assault
against the salient, for
