If you read through Cetti's link, you will find reference to the East Surrey's dribbling footballs forward whilst attacking. My father (sadly no longer with us) was in one of those groups and I still have the cap badge and one shoulder flash worn by him during that attack (after five hours of fighting he was wounded, hence the missing shoulder flash). One of his brothers simply vanished from a shell burst during the first battle of Ypres and his name is inscribed on the Menin Gate. Another was killed during an advance towards the Somme and is buried in a war cemetery in Poperinge. Four of his cousins were wounded together in a group and were taken to the military hospital at Etretat. All died, and their headstones are still in the hospital military cemetery there.
