ere very energetic on the 11th. Conneau's
Cavalry Corps pushed back the German cavalry to the line
Vermelles--Richebourg--Vieille Chapelle. De Mitry's Cavalry Corps
assembled and drove the German cavalry back to the line of the Lawe at
Vieille Chapelle and Estaires.

By the night of the 11th, the Cavalry Corps under Allenby had made
good a great deal of ground to the north, and were halting between
Wallon-Cappel (west of Hazebrouck) and Merville. Moving thence on the
morning of the 12th, they carried out invaluable work during the
subsequent two or three days. Allenby liberally interpreted his orders
and made a magnificent sweep to the north and north-east, driving the
enemy back all the way.

Of all the splendid work performed by the cavalry during the war,
little can compare (in results achieved) with this advance. It was
only surpassed by their immortal stand on the Wytschaete--Messines
ridge on those ever-memorable days and nights of October 31st and
November 1st.

By the evening of the 12th, Gough, with the 2nd Cavalry Division, had
attacked and captured the Mont des Cats position, which was a
strategic point of great importance lying six miles north-east of
Hazebrouck. There was great opposition by the enemy cavalry, which was
supported by jaeger and strong infantry detachments; but Gough carried
all before him in fine style.

The 1st Division under de Lisle halted before Merris, after severe
fighting which drove the enemy back many miles.

On the 13th, the cavalry made a further great advance,
driving the enemy before them, and on the evening reached the line
Mont Noir--Boeschepe--Berthen. The position of Mont Noir was
vigorously defended by the Germans, but they were finally driven out
by the 2nd Cavalry Division under Gough, who handled his troops with
great skill and determination.

On the 14th, the 1st Cavalry Division reached the area
Dranoutre--Messines and pushed advanced detachments to Warneton. The
2nd Division moved to the Kemmel--Wytschaete area, sending advanced
detachments to Werwick.

I sent instructions to Allenby to make a strong reconnaissance of the
Lys from Estaires to Menin on the 15th, and report the result as
quickly as possible to me at the Headquarters of the 3rd Corps.

Late at night on the 12th, the 3rd Corps (4th and 6th Divisions and
19th Brigade) moved to the area east and south of Hazebrouck. The
infantry were moved in motor omnibuses.

On this day General Headquarters w
