To be honest I dunno what is up with everyone being from Arcadia. :)The only thing I am not sure about is this second battle of Arcadia mentioned in Björkgård history. There wasn't really a second battle. After the first battle UNSC presence on the world disappeared and a vast majority of the population abandoned the world. All that remained was a few farming communities that continued to supply the UNSC. By the time of the glassing of Arcadia the world was pretty lawless and lacked permanent UNSC fleets or land forces. The glassing was pretty much a massacre.That being said, there really isn't much canonical information on the fall. So there isn't anything to say that there wasn't some form of UNSC resistance.

Aside from the farming-village, there was a transient drydock to refit returning ships as per Cole Protocol Article 4. Pretty much stating that UNSC vessels no matter how damaged are not permitted to slip-space to core-worlds.

There was also a Forunner dig-site.

UNSC Chara happened to be damaged and near the end of a refit during the fall.
