It means no retreat, no plan B. Only forward, always. Success or death. All or nothing.
In 1519 the Spanish conqueror Hernando Cortez found him and his army going against the much, much larger and more established Aztec army.
Some of his men, scared, started speaking of retreat and when Hernando go wind of this he ordered all the ships to be burned so there would be no possibility of retreat. They would either win the battle and go home in the enemies ships or die.
Having this no form of retreat mentality helped them to win the battle.
Burn the boat means spending ALL of your energy on the single-focus of plan A - and not diverting your attention at all for a plan B or C.
It means being completely determined to achieve the goal.
