WW1: Experiences of an English Soldier
This blog came to my attention a while back - no longer sure exactly how - and I've been following it along over time. The writer was posting letters that his grandfather had written during his time in the British army during WW I. What made it especially interesting to follow was that he was posting each letter exactly 90 years after it had originally been written. At this point it is something of a static artifact, since the events it chronicled have come to an end, but it is still fascinating reading. There is also a lot of additional material that has been added along with the letters to help them make sense to us in this day. If you like history, and particularly the history of the Great War, then this is something you really shouldn't miss.
