Regarding the Falklands conflict from the 'other side', I have a translated Spanish publication titled 'Falklands Witness of Battles', by J. R. Briasco and S. M. Huertas
This contains a lot of reports and photos from the Argentines, including one chapter detailing the attack on HMS Invincible.
Well, they are spanish authors, not really "from the other side".
I am finishing "The Golden Horseshoe", the wartime career of Otto Kretschmen, WW2 U-boat commander. Really good read!
