I know of 3 local swarm who attempted to defend Dover. There were probably 3 more who knew what was happening but decided to let it fall. I'm also quite sure there were plenty in missile range that knew but did nothing. Going into the battle we had absolutely no idea what to expect, I never for one second thought it would go down like this. They were completely overwhelmed and didn't know what to do, plus their days were numbered anyway. The point of building a 31 million Bot tower isn't about how to defend it, it's more of a who on earth would ever actually think they could destroy it.
