Role in the film
Pursuing the "Black Pearl", "Endeavor" went to the barrel with the body of the dead soldier of the company, bound from above. Greitzer helped Lord Beckett, using a knife from his pocket, to cut the bottle from the wrist of one of the corpses.

Then Greitzer noticed another body in the water, the path left by Will, so that Beckett would follow him. Greyzer doubted whether or not there was a traitor among the crew of the Black Pearl, or if it was just a trap set by the pirates. Lord Beckett told him that this was nothing more than a gambit of an experienced adversary, and ordered Greytser to regulate the Endeavor course, hoping to catch up with the "Black Pearl" before their bodies run out.

He was aboard the Endeavor during the Calypso battle of Calypso. When they were ready for the final stand, to destroy the "Black Pearl" along the Pirate Armada. When the Flying Dutchman came out of the water, and Will Turner, as the new captain, ordered to shoot at Endeavor, the Pearl also began to shoot at him. His fate is unknown. It is assumed that he died in the explosion Endeavor.
