Met Elkington today. (He now commands our Artillery.) He came to tea. Only arrived from Ypres four days ago, where he had been for four months, shelled day and night. Has been out 14 months; home twice for 5 days. Never touched and never a day sick. Right through the Retreat from Mons, Marne, Aisne, etc. Looking very well, but tired. Very cheery, and just the same as ever. Says War Office & General Headquarters and the French very optimistic. They all think we have the Huns, and at least they are at the end of their men.
