Some 22 battalions of the York and Lancaster saw service during World War One. During this time, for Other Ranks, the usual form of headress was the soft cap (often reffered to as a trench cap).
The badge is the normal Tiger and Rose pattern badge with an oblong sweat hole to the rear of the coronet and 4 small circular sweat holes around a larger circular sweat hole to the rear of the Rose. The badge is fitted with a slider.
The cap is a 1916 pattern soft cap and was more commonly worn outside the trenches as the normal head dress from 1916 onwards in the trenches was the steel helmet.
