Abandoning of Mazovia

The Abandoning of Mazovia, also known as the Massacre of Mazovia, or Fall of Mazovia was a controversial military disaster by the. The UNSC's failure to evacuate the colony and refusal to disengage the far numerous fleet ended with the entire UNSC fleet stationed in the system being annihilated and the colony being glassed. A day later, a UNSC battlegroup entered the system to reinforce the now destroyed UNSC fleet and were ambushed by the Covenant. This second naval engagement however saw the total destruction of both Covenant and UNSC fleets.

Luckily, the surviving Mazovians were spared from incurring anymore of the Covenant's wrath, as the Covenant either did not care for the colony anymore, or believed that the colony was eradicated. The UNSC on the other hand, refused to send out a scouting party to the Eta Leporis system or attempt to evacuate the rest of the colonists, despite pleas from former inhabitants of Mazovia. Instead, the UNSC and branded the battle as the Fall of Mazovia and claimed that all colonists had perished.

When it was discovered that Mazovia had survived the war nearly twenty years later, the full details of the military coverup were declassified and released to the public. Several days later, the, United Nations Space Command, and Office of Naval Intelligence found themselves in several lawsuits by outraged and distraught Mazovians who fled their world. It would become one of the largest scandals and controversies in human history.
