About 10-30 p.m. on May 10th, C.S.M. W. Medley, M.M., with eleven other ranks of B Company, left the front line, crossed No Man’s Land, and reached the enemy wire. There he left six men to form a covering party, and, cutting a passage through the wire, entered the enemy front line with the remainder of his patrol. About seventy yards to his right was an enemy sentry post, but he decided to attempt nothing against it as it was difficult for anyone to approach without being observed. He crossed over to the enemy second line, passed that also, and continued straight across country until he reached the third line. The patrol was now about six hundred yards in rear of the enemy outposts. Leaving the rest of his party in an old shelter, the patrol leader went forward alone to reconnoitre. He reached a communication trench, known as Serpent Trench, and saw a man walk along it. He returned and brought up his men, getting into the trench with two of them, and leaving the rest on the parapet. They were barely in position when three Germans--afterwards found to be a water-carrying party--came along the trench. C.S.M. Medley called on them to surrender and they at first laughed, probably thinking it was a joke of their own men; but, presently realising that they really were face to face with a British party, they turned and ran. The parapet party immediately opened fire and killed one German; Medley pursued and captured a second; but the fate of the third is unknown. The prisoner was promptly hoisted out of the trench and the patrol returned by the way it had come, reaching the British line without loss after an absence of more than four hours. The prisoner turned out to be a machine gunner of the 3rd Bavarian R.I.R. (1st Bavarian Reserve Division), a most valuable identification, since it proved that a relief had taken place opposite the Battalion front, and that one of the German divisions which had been shattered at Vimy was now holding the sector. It was to receive this news that Brigade H.Q. had been disturbed in the early morning.
