When archivist Angus Johnson started to read through his copy of Alanbrooke's War Diaries, he did some digging in the archives to see if this important, but lesser-known figure from WW2 turned up in any papers. It turns out that Alanbrooke had visited Shetland and was a bird watcher. He spent time with the Kearton brothers who were possibly the world's first professional wildlife photographers.
