I think you guys would be interested in this -
The Great War, a YouTube WW1 documentary series.
They do a main episode every week, detailing events of that week 100 years ago.
So it’s still an ongoing series and will be til late 2018.
They also do side episodes on specific topics, at least once a week for that too.
The main episodes are in playlists for viewer convenience too, having each season for each year the war takes place in.
Here’s the playlist for 1914, which is where you ought to start off if you’re interested.
Definitely a worthwhile watch if you are particularly interested in WW1 history, I personally find it a joy to look forward to the next episode every week. Keeping up with the war on a weekly basis.
