Battle of Cirith Ungol

The Battle of Cirith Ungol was a vague fight between the Orcs of Barad-dûr and Minas Morgul and Uruk-hai stationed at Cirith Ungol over Frodo's mithril vest. The commanders of the two sides were Shagrat and Gorbag. The fight allowed Sam to sneak in the tower then he was able to find Frodo and rescue him. Every soldier stationed at the tower was killed except Shagrat, managing to get away with the mithril coat; and he took it to Barad-dûr.
