In the First Battle of Ypres, when the small British Army bolted the door of the North against the German sweep, his Division played a foremost part. In General Smith-Dorrien's advance towards La Bassée it moved on the left flank, clearing out the Germans from the forest of Nieppe, the Hill of Cassel, and Hazebrouck. Along with the 1st Cavalry Division it reconnoitred the line of the Lys, and later held the front between Zandvoorde and Messines on the left of Allenby's Corps. In the great struggle of October 30th and 31st it had desperate fighting to hold the line, and, on November 1st, before the French XVI Corps arrived in support, it was forced back from Hollebeke and Messines. [Illustration: GENERAL SIR HUBERT GOUGH] Sir Hubert Gough's 2nd Cavalry Division was at the Battle of Neuve Chapelle, but failed to get the expected chance of going into action. Shortly after this he took command of the 7th Infantry Division and was engaged in the operations at Festubert. About the middle of July, 1915, he was appointed to command the I Corps in succession to Sir C. Monro, who went to the Mediterranean. At Loos Sir Hubert Gough commanded this Corps, which contained at the time the 2nd, 7th and 9th Divisions. It was his men who stormed Fosse 8 and the Hohenzollern Redoubt. During the spring of 1916 he was put in command of a Reserve Army, which at the time consisted chiefly of Cavalry and a Staff. After the first day of the Battle of the Somme, when it was apparent that Sir Henry Rawlinson's Fourth Army was engaged on too long a line, the part of the front from la Boiselle northwards was handed over to the Reserve Army, which now became known as the Fifth. There, for five months, Sir Hubert Gough was hotly engaged. It was under his command that Pozières and Mouquet Farm were taken by the Australians and Courcelette by the Canadians, and the Thiepval Ridge cleared at the end of October. His greatest success came in the Battle of the Ancre on November 13th, when, in two days, he took more than 5,000 German prisoners. When the German retreat began in the spring of 1917, Sir Hubert Gough's Army operated in the Bapaume area and towards the country between Cambrai and St. Quentin. It was engaged on the right of the Third Army during the Battle of Arras.
