In 2525, then Vice Admiral Cole led a battle group to Harvest following the unprovoked attack by the Covenant on that peaceful agricultural colony. After a hard won battle, Cole and the battle group returned to Earth only to learn that other colonies had been destroyed as well.

At the top:
Then it lists the men and women's names:
And at the bottom it states:
- One of the names in the left plaque is Chen Agu, possibly a relative of the ODST Kojo Agu.
- The monument also shows that ONI believed that Dr. Halsey was killed on Reach, when she actually is alive in the Micro Dyson Sphere inside the Shield World Onyx as of November, 2552. This is previous head of ONI Margeret Parangosky's doing, as she had a 'feeling' that Halsey was still alive but marked her as KIA for SPARTAN and UNSC morale reasons.
- The memorial incorrectly lists Preston Cole's date of birth as April 4, 2484, when he was in fact born November 3, 2470.
- On the left plaque, it says that they gave their lives for the human race, while on the right it says they gave their lives for the UNSC.
