First was Osprey Raid #4: Who Dares Wins: The SAS and the Iranian Embassy Siege 1980. Now, I vaguely recall this taking place, however at that point, I was in medical school, and rarely caught the news due to our work schedule. the book details how quickly this event took place, which is part of the reason I can barely remember it. I found this a very interesting read about the entire event.
Second was Osprey Raid #: The Blocking of Zeebrugge : Operation Z-O 1918, a WWI raid by the British into German-occupied territory across the Channel from England, in an attempt to deny a port to German Naval units. I didn't find this one as fascinating as the previous book, but it had moments of interest.
