No there was Bravo 20, then The one that got away but then there were tow other published later - Bravo 20 the true story and Eye of the Storm - the later two being written by an ex SAS sergeant and the S/Major of the SAS at the time.
The later two books refute many of the facts of Bravo20 - and The one that got away - specifically in the amount of contact the patrol and the escapee had with the enemy forces.
Someone obviously felt that they had to exaggerate the story so that the masses of enemy turned out to be three farmers with a rifle as stated above.
Two of the team died of hypothermia, 1 got away after evading for a week and walking to Syria, one was killed by local policemen after a firefight and the rest gave themselves up - after which time they were interrogated and from their own accounts tortured.
However since the rest of the story has large holes in it one has to wonder how much of the torture is true - they all survived capture which is the most dangerous time of surrendering - especially to what were basically militia.
The Bravo20 true story was on TV - actually showed the terrain and their exact positions, inteviewed the Iraqi farmers and the policeman involved - was pretty interesting. They were lucky to come up against civilised people - many parts of the world they'd have been killed when trying to surrender.
