Picard was the first 6 star admiral in Starfleet history - a position thrust upon him during the final Borg conflict (As initiated by the Borg Blitzkrieg and total assimilation of Romulus, Vulcan, Cardassia prime, Kronos, and Ferenginar). The scattered remnants of those societies became full members of Starfleet in short order to mount a final defense. The conflict was won when, knowing that his unparalleled knowledge of starfleet strategic information and former status as Locutus of Borg gave him special significance to the Borg, Picard surrendered himself to the Borg willingly... ...With a Borg logic bomb installed in his remaining Borg implants. Within a matter of months, every Borg in the galaxy ceased to function as the virus spread. Picard's sacrifice, and the resulting peace between nearly all the races in the quadrant cements him as one of the most venerated figures in all of history. However, since that all happened after the events of Voyager, it hasn't been documented yet.
Shortly afterwards the answer was marked for deletion by two users; @K-H-W and @DarthMelkor, then power-deleted by a community moderator (i.e. me).
After discussing the situation here, this is a clarification on the question, why was this answer deleted?
