I’ve always liked naval history. So I was pleased when several days ago this movie of Royal Navy ship movements during World War I was released. Using data from navigation logs, it plots the locations of the UK’s naval ships throughout the course of the war and so when played out over time you see the changes in those positions. The screen capture below shows just how much the UK depended on guarding the trans-Atlantic convoys. But also note the UK’s operations on rivers deep inside China.

My only complaint is that I could not find a way to slow it down or pause it once it had started.
