The Battle of Alpha Aurigae was a major battle in the early years of the Human-Covenant war. The human fleet, consisting of 117 ships, engaged 12 Covenant warships, destroying the enemy force but losing a total of thirty-seven ships in the process. It was one of the rare naval "victories" for the UNSC.
- Although the short story The Impossible Life and the Possible Death of Preston J. Cole clearly states that Preston Cole had one hundred seventeen ships under his command, Halo Wars: Genesis states he only had one hundred seven. The reason behind this ten-ship discrepancy is currently unknown.
- At least 3 of the Covenant ships engaged were CAS-class assault carriers, and at least two were CCS-class battlecruisers.
