Cut content.. Full game files has Ulfric at every battle giving the speech as well as fighting.
Exactly, it was cut. In Oblivion the Champion became a member of the Elder Council as the Duke of Colovia, except it was cut and the only thing remaining was the Colovian Signet ring.
Full game (Without cuts) has Elisif and Jarl Balgruuf being killed. Also you could expose Runil (Falkreath Priest of Arkay) for being ex Thalmor:
"They are the governing council of the Aldmeri Dominion. They lead us to attack the Empire and forced the Empire to agree to stop worshiping Talos. It was during the war with the Empire that I was at the height of my power. As a Thalmor battlemage I laid waste the enemy. Men, women, children, no one was spared my wrath. I destroyed whole villages."
Some things that are cut would make the game so much better, and the lore so much richer. But alas, if it doesn't make it into the final cut, it is gone.
