The Wages of War and To Gorgoroth are two missions as part of the Gondor storyline in Middle-earth: Shadow of War.
These unlock one after another, and come after completing Allies, Blood Sport and The Uninvited.
If you are interested in completing other missions in the game, our Shadow of War guide and walkthrough can help.
The Wages of War
Prerequisite: Complete The Uninvited.
Reward: 10625 XP, 960 Mirian
Rescue the Gondorians: Once the third of four is free you'll be interrupted.
Defeat the Captains: Gubu Skull-Splitter and Garl the Strong show up to ruin your day. They're both easily stunned and vulnerable to ranged weapons so we took the strategy of keeping one immobile and firing off a few shots at the other to keep them at bay until we were down to one, and then it's a simple fight.

Prerequisite: Complete Wages of War.
Rewards: Iron Guard skill upgrade, 11370 XP, 970 Mirian
Find Baranor / Rescue the Gondorians: Head towards the marker.
Rescue Baranor / Defeat the Captains: Zunn Bone-Licker and Skak Taskmaster are your opponents, but Idril will show up to fight by your side.
You can try and rescue Baranor while the fight is in progress, but we'd suggest just dealing with the threat first.
