The 1st Legion was the name of the Alliance military forces who accompanied Prince Arthas in his quest to Northrend to destroy the dreadlord Mal'Ganis. They were ultimately betrayed and slain by Arthas before being raised as undead.
It is quite likely that the 1st Legion was also the force which accompanied Arthas in his campaign through plague-ridden Lordaeron as seen in the Warcraft III human campaign.
