A pirate's treasure...
Billy the pirate buried his plunder at the mouth of a large river. He killed all of his crew then made his way on foot back to civilization. He ended up getting sick with yellow fever and died in a hospital bed.
Just before he passed he whispered to the nurse the coordinates to the buried gold. The nurse believed it was the high fever and delirium, but he insisted she write it down.
Many years later her great-grandson Jack, while packing for the second Great War, found the note in a box belonging to his long dead relative. Not knowing the importance of the note, he sent a telegram over the wire to his grandfather who was still living in DC.
Unfortunately the message never reached his grandfather: the Germans had intercepted the telegram. The U-boat captain prepared to send the message back to high command, when the sub hit a mine.
My grandfather found the message during a salvage operation. Can anyone help me find the gold?

It's probably an easy one to solve. I can give a hint if necessary.
