Here's the real question: was the SS Beagle armed('Bread andCircuses')? In other words if things went pair shaped how long till help?
Very realistically posting.
Because she was missing for six years...
The next question is did any of her crew try to send an emergency message? And were they stopped from doing so? By her Captain?
In other words how stupid were they? The Captain, was...but what about the rest of the crew?
And this gets back to the American pioneers of the nineteenth century. They can be divided into three groups. The first group, 'we don't need guns, except for occasional hunting. ' The second group 'Yah, we need guns...zzz, say what? And the last group were at the ready - not bothered.
The last group always showed that they were willing and able to defend themselves. Pretending that there are no hostiles "out there" even gangs of Europeans is not something that produces long life.
In still other words, how much were/are ships like the SS Beagle like the Dutch East India Company?
If commercial ships were expected to surrender and die, then what is the point of going out there to die? In other words if you stayed home, you would be a prisoner of United Earth...
