D.

d. simply denotes a soldier died, usually as a result of sickness such as dysentry, colitis, pneumonia or malaria etc. It could also denote an accidental death such as a firearm discharge. It was a term used widely throughout the First World War along side k.i.a. (killed in action) and d.o.w. (died of wounds). All three were used exclusively in the 1921 War Office publication Soldiers Died in the Great War.
