Sec.-Lieut. SYDNEY R. ALLEN,
16th Battalion
MANCHESTER REGIMENT.
THE Somme Battles of 1916 had no equal in all the war's history in the innumerable deeds of heroism they produced. Several volumes could be written of these narratives of individual gallantry.
   Sec.-Lieut. Sydney R. Allen, of whose part we are now about to write, was one of those officers who died on the first day of that great offensive, and it was to the high courage which he and so many others displayed that so large a tract of territory was subsequently wrested from the enemy's tyranny.
   Young Allen was the twenty-two year old son of Mr. and Mrs. George T. Allen, of Alexandra Road, Claughton. Educated at the Great Crosby Merchant Taylors' school, he was apprenticed to Messrs. Alfred Dobell & Co., the well-known firm of timber merchants, with whom his time should have expired in 1915. But the year before the war had begun, and he was one of those splendid patriots who immediately left their homes and future, sacrificed all ideas of comfort and commercial ambitions that they had planned for themselves, and responded with alacrity to the call of duty. He joined the 6th King's (Liverpool Regiment) three days after was was declared, and went out to France in February, 1915, an eager Territorial, as one of the "First Hundred Thousand."
   Speedily showing his mettle, he was given his commission in the following month, and his further military service was with the 16th Manchester Regiment. With this Kitchener unit he saw a lot of hard fighting, and it was in Montauban, on the 1st of July, 1916, that he was killed instantaneously when leading a bombing party towards the German lines. He was a brave and selfless-minded officer. Once, indeed, he saved the life of a brother officer by going out and carrying him back to safety though the enemy was only forty yards away. In this errand of dauntless pluck he was wounded severely. Such an officer was bound to be an inspiration to his men, and those who served with him most certainly did fight with all the more ardour under the stimulus of his fearless, resourceful leadership.
