The firm responsible for archiving the First World War soldiers' wills that are going online said they reveal some "quite interesting" emotions.
Iron Mountain commercial director John Apthorpe said:
With 230,000 individuals who died in the war, the emotions [that come through] are quite interesting when you read some of the notes they left.
A lot have straightforward statements, but some of them do have personal letters and touches, and a bit more detail about what's happening.
The wills, classed as official records, were only previously accessible through direct requests.
