Stab

As Lord Bernard started his long speech, Anoon very deftly had the flagship disengage, before quietly beginning to make toward their new destination- the Royal Harbor, leaving the common crew on the other ship largely none the wiser.

After the great losses they had suffered and the impossible sight of a literal bridge coming down, these men were far more engrossed in what Lord Bernard had to say and sought to soothe their aching hearts with the promises being made.

Furthermore, Lord Bernard had cleverly positioned himself such that the soldiers faced away from the moving ship.

So it was only after Anoon had already advanced quite a long distance that one of the men spotted the ship's sails moving in the opposite direction, and worked to quickly shout, 

"Hey! Where are those guys going? Look! Look! They are abandoning us. Those craven swine! Those traitors!"
