At 10 A.M. on 17th May, after a telephonic conversation with General Anderson, it was arranged that we should seize any opportunity of advancing into the enemy trenches. The Sirhind Brigade was again placed at my disposal, for the purpose of ensuring touch being kept with the left of Second Division in any advance which the latter might make. At 11 A.M. the First Army directed that the duty of gradually establishing a defensive flank on the left as the attack proceeded, was assigned to the Indian Corps, and that as the attack of the Second Division progressed we were to gradually extend to the right and relieve troops of the Second Division as opportunity offered. The Bareilly and Sirhind Brigades were detailed for this duty. At 3.30 A.M. on 18th May the Germans attempted an attack on one company of the 15th Sikhs, but were bombed and driven back. During the progress of reliefs of certain battalions of the British Brigade on our right the 1st Highland Light Infantry had five officers and seventy other ranks made casualties, including Lieutenant H. S. Davidson killed. It is interesting to note here that the 1st battalion which belonged to the Indian Corps actually relieved their own 2nd battalion which belonged to the British Brigade fighting by our side. A chance meeting under such conditions is rare, even under the varied circumstances in which the British Army serves. This 18th day of May was to witness a deed of heroism which for sustained gallantry can surely not be surpassed. A British officer and ten men of the 15th Sikhs were those who added a brilliant page to the history of the Indian Army. Of the ten one Lance-Naik Mangal Singh and three sepoys belonged to the battalion, whilst four of the others were attached from the 19th Punjabis and two from the 45th Sikhs.
