Some Up-to-Date Gas-Coves, who are teaching the Boches the Game of Tit for Tat. Caricatures by Lieutenant Fred May of various men at a famous gas school (in an undisclosed location in Britain), where the rudiments of attacking with gas were taught. The Germans first used gas at Ypres in 1915, and the wording of this cartoon implies that the British have been forced to counter attack with the same method. People pictured are Lieut A.W.J. Lindsell-Stewart of the North Staffordshire Regiment, Lieut R.R. Garnham of the Royal Field Artillery, Captain F Gillespie of the Manchester Regiment, Captain Spedding of the Durham Light Infantry, Major H. E. Burton of the Royal Engineers, Lieut J.U.G. Slack, M.G.C, Captain W. Williams of the Welsh Regiment, and Lieut M Myers of the Royal Flying Corps.
