On the 19th the Battalion was relieved by the Royal Welsh Fusiliers, and went into the reserve trenches in front of Gorre, and on the 21st into billets at Les Choqueaux. On the 24th it returned to the trenches between Givenchy and La Bassée Canal, and on the 27th was relieved by the Border Regiment, and went into billets at Le Preol. On the 20th Lieutenant Sir A. Napier joined, and on the 23rd a draft of sixty-seven men arrived under Lieutenant R. Wolrige-Gordon and Second Lieutenant G. J. T. H. Villiers. Lieut.-Colonel Corkran wrote to Colonel Streatfeild, and asked that some drums and fifes might be sent out, and Lord Derby, who paid a visit to the Battalion, promised to procure them and send them out. In the meantime eight men with some musical skill came forward, and offered to form a drum and fife band. The instruments arrived at the end of the month, and were a great success. The band now consisted of six drums and twelve fifes, and marched at the head of the Battalion for the first time on the 30th, when it moved to billets at Busnes. [Sidenote: July.] The Battalion had a good rest, and remained in billets till the 17th of July, when it relieved the Yorkshire Regiment in the trenches at Quinque Rue. [Sidenote: July 1915.] On the 13th Lieut.-Colonel Corkran was promoted to the rank of Brigadier-General, and given command of the 5th Infantry Brigade. His departure was much regretted by the whole Battalion, which had the greatest confidence in him. Major G. Trotter then assumed command, and his appointment as Commanding Officer was confirmed about a week later, and gave universal satisfaction. The Battalion remained in the trenches from the 17th till the 26th, when it withdrew into billets at Calonne. During the time it was in the trenches there were but few casualties, among them Lieutenant C. G. Goschen, who was wounded in the thigh. While the Brigade was in billets the officers of the 1st Battalion entertained the officers of the 2nd Battalion at dinner. The Prince of Wales and Captain Lord Claud Hamilton also attended. A few days later the coming of age of Lord Stanley gave another opportunity for a gastronomic triumph composed mainly of bully beef and Maconochie rations. The flies in these hot days became unbearable, and fly-traps and fly-papers were sent out in some measure to mitigate this plague. [Sidenote: Aug.] On August 3 the Battalion received orders to join the newly formed Guards Division. It was not without regret that it left the Gordon Highlanders and Border Regiment, alongside of whom it had fought for nearly a year, and with whom it had shared the glorious reputation which had been earned by the Division. All the battalions of the Division prepared entertainments to bid them farewell, but the notice was so short that these invitations could not be accepted.
