Cole's personal log
From Halopedia, the Halo wiki
Cole's personal log was an audio record kept by Vice Admiral Preston J. Cole of his private thoughts and musings. The log's files included Cole's recollections of his involvement in important events such as the Callisto Incident and the early naval campaigns of the Human-Covenant War. Cole began the log sometime before 2541 and made his last entry in February 2543.[Note 1]
An excerpt of and several quotes from Cole's personal log were included in the report Historical/Psychological Analysis of Cole, Preston J., sent by Codename: SURGEON to Codename: USUAL SUSPECTS in 2552. SURGEON cited one of these recordings as evidence that Cole "had reached the nadir of his spirits" by the time of the Battle of Psi Serpentis, suggesting this as evidence of conditions which might have prompted Cole to consider defecting from the UNSC.
In the report, SURGEON quotes Cole from an unspecified entry on the "Callisto Incident" of 2494, recorded sometime after the fact. Evaluating the tactics he used to force the surrender of the Insurrectionist-controlled UNSC Callisto, Cole noted that because of his violation of Common Space Law he could no longer plausibly send distress signals while in enemy territory: "No one would believe it. Surrender, quite literally, is no longer an option for me."
