Up at 5 o’clock. Breakfast at 6 o’clock. Paraded at 8.45 and went to the big parade ground. Were lectured on gas helmets, given one each, and put through a gas test. Our buttons nicely blackened1. Very interesting. Heavy shower as we sat. Wrote letter to Mr Inwood in the afternoon. Went to lecture by an Indian doctor at night. Went to bed shortly after 9 o’clock.
Received news of North Sea fight2.
“Our buttons nicely blackened”: Following the first use of gas by the Germans at Ypres, a team of scientists was sent to Belgium to find out what gas was being used. They identified chlorine from the way it had discoloured buttons on soldiers’ uniforms. Given the blackening of buttons noted here by ALL, it seems likely that chlorine was also the gas used for this test. ↩
