The term 'REAR, TO AN ADMIRAL' is a phrase used to describe the two parts of a naval vessel. The first part is the STERN, which is the back end of the ship and is usually the highest point. The second part is the AFT, which is the area behind the STERN and is typically the lowest point. Together, these two parts form the rear of the ship, which is the area of the vessel that an admiral would be in charge of.
