Can somebody show me the evidence for Talos being the three guys from above? I've not been here in a while and I'm pretty rusty and I would like to read the in-game sources that indicate this.

Unless I've gotten something completely wrong and this isn't true at all.

Which appears to be confirmed in TESV by http://www.uesp.net/wiki/Skyrim:The_Ghost_of_Old_Hroldan.

Skyrim confirms that there was, at the very least, a breton named Hjalti in charge at the battle of Old Hroldan.

Ninja'd while watching tv
