He claimed to be out to tell the truth on the raid that killed Osama bin Laden.
But the Navy SEAL who wrote the first hand account of the mission could actually have been motivated by revenge – on his own comrades.
A rival book alleges that Matt Bissonnette, who wrote ‘No Easy Day’, had ‘bad blood’ between his former colleagues and commanders because he was kicked out of the unit.
‘No Easy Op’ claims that the soldier was ‘ostracized’ when he inquired about leaving the Navy to start a business and was sent home suddenly before quitting.
No Easy Day, which is due out tomorrow, is the first account of the bin Laden operation from a member of the squad who was there.
But it has proved controversial because Bissonnette, writing under the pseudonym Mark Owen, did not seek approval from the authorities before he wrote it.
It also disagrees with the official White House version of events which was put out at the time and has caused the Obama administration consternation.
According to the New York Times, the book says that Bissonnette was ‘repaid for his honesty and 14 years of service’ with nothing but rejection.
In a statement, Kevin Maurer, one of the co-authors of No Easy Day said: ‘After spending several very intense months working with Mark Owen on this book, I know that he wrote this book solely to share a story about the incredible men and women defending America all over the world.
‘Any suggestion otherwise is as ill informed as it is inaccurate.
‘What’s more, Mark has an unshakable respect for the US military, in particular the men he served with.
‘That’s why not one negative word was written about anyone he served with.’
