This is what I was referring to:
https://www.cbsnews.com/news/diplomat-us-special-forces-told-you-cant-go-to-benghazi-during-attacks/
Excerpt from the link above.
“The deputy of slain U.S. Ambassador Christopher Stevens has told congressional investigators that a team of Special Forces prepared to fly from Tripoli to Benghazi during the Sept. 11, 2012 attacks was forbidden from doing so by U.S. Special Operations Command Africa.”
Excellent link...The book was written by the people on the ground at the scene...It mostly covered the events that they witnessed and defended and initiated to save lives...
As I earlier said, the book is very non-political and stayed pretty much away from any political action that may have taken place during the action...
