I left it ambiguous in regards to Nagamasa so as if we need to use his character for anything later we could. He could be dead or alive. All the same your unit could have been a part of the units Nagamasa's force attack only to result in a defeat for his unit leaving the commander's fate unknown.
As for Jack's Gang it's possible that could also be a thing since they don't like britannians coming into their territory.
