## Battle

### Regret's Arrival

The Fleet of Sacred Consecration was detected on it's way to Earth, prompting a quiet dragging of available ships back to Earth all morning. They were later detected near Io as a series of Slipspace "whisperers". Probes were sent to investigate but shortly afterward the Covenant fleet reverted to realspace near Earth, just outside the killzone of the planet's Orbital Defense Platforms (ODPs). UNSC forces went to TACCON Alpha 2. Fleet Admiral Harper ordered his battle group to attack, but quickly received new orders from Fleet Admiral Terrence Hood to fall back and defend the ODPs. Having expected an overwhelming enemy offensive in the style of the Battle of Reach, the relative weakness of the attack puzzled the defenders.
