Great action. Very accurate in most scenes. The director deserves a lot of credit for making a very good movie with a tiny budget. The actors are excellent. The Irish did a fantastic job against all odds fighting a massive group, many times the number of the Irish.
Yes the Irish did surrender but they ran out of water, food and ammunition, which the UN was supposed to have supplied but did not and could not supply these brave men. They did have a great commander who knew how to fight a defensive battle.
