My impression of the completion of War Diaries is that the task was often considered an onerous one by the officer detailed to prepare it. However, in the case of Edmund Blunden,the War Poet, and reading some of those he wrote, I think he relished the task. Praise was given where appropriate, both to individuals and his battalion as a whole (11th R. Sussex). The choice of language and the style of writing suggest that here was a writer who enjoyed using his skill with the written word.
Not so in respect of an entry I once read : "A quiet day. 1 OR killed".
