He is a sour man.
A Game of Thrones
When Tyrion Lannister is taken captive by Catelyn Tully, Lord Tywin calls his banners and raids the Riverlands. Lord Lefford joins his liege lord in the campaign. He is given charge of Lord Tywin's stores and supplies.
When Tyrion joins with the Lannister camp on the east bank of the Trident, Lord Lefford provides him with a tent and is charged with supplying weapons to the hill tribes Tyrion has recruited to join the army. He reluctantly hands over his arms to what he calls savages, being particularly displeased when Shagga demands two axes.
When a messenger arrives with news of the defeat of Ser Jaime Lannister's forces in the Battle of the Camps, Lord Lefford suggests forming a truce and exchanging prisoners with the Stark army, pointing out that Queen Cersei also has Sansa and Arya Stark in her hands. When Ser Addam Marbrand says that Robb Stark would be foolish to accept exchanging his sisters for the Kingslayer, Lord Lefford then suggests ransoming Ser Jaime, but Tyrion correctly predicts that they will not offer ransom.
