Very interesting. Its amazing all that you can learn from letters. What is important to the avereage guy is often times more interesting than the clinical description of the battles.
My English is not great as you know, and read the handwriting is even more difficult... But I agree with CaptO. When I read the book of my grandfather's letters from the front of the Great War.... is not just history; is the "HISTORY" of a person, with his fears, his anger and sorrow for the loss of friends and companions. As an example, my grandfather was very angry with the "imboscati" ("imboscati" were those who were hidden during the First World War not to be enrolled...). In a letter received, he tells of his acquaintances, that they were angry because they could not find a home for the holidays.... holidays... while my grandfather was in the forefront....
In another letter he tells how he could shoot two Austrian soldiers from behind a rock .... they were intent on urinating ... but my grandfather did not succeed, because he thought that those two boys, had a family at home waiting for them, just like him. There are many small "paintings" of the life of a soldier, some funny, others less, but they are much less sterile of "history" itself.
