The People Before the Settlers to Canada and Australia
We talk or think about the early settlers to North America, and Australia. But, those people chose to arrive in the New World(s). They would have expected to forage, build a shelter and later a home. It would have been much more than they expected, but they had some experience in finding food, and so on. They came with supplies too.
I seldom read about the convicts who were sent to Canada, US, and Australia. Were some sent to other places too, before they places had European given names? They would have grown up in the cities, rural if they were lucky. How would they have felt after starving in Europe, stealing, lying, cheating, desperate for basic needs like food and shelter?
Now here they are... there's nothing as far as human habitation. Sick and worse for wear to say the least, travelling on the ship for months. Before people built a colony, a settlement, a group shelter, an outhouse. Before any of them knew about native people - even if they could find a way to communicate with them and not be afraid of those "savages".
To land on the shore of Atlantic Canada with nothing but the clothes on your back and whatever might be in your pockets. After being in jail, shuffled along to the ship, the sea voyage which would have taken months. Here they are, get off the ship and what... go climb a tree? The forest would be thick. Only get thicker as they tried to enter it.
Do they know what to eat? Some will poison themselves due to not knowing what is safe to eat. No one would be there to help them if they were sick, if they were injured, if they just wanted to go home again. If they grew up in a city, do they even know how to forage for anything edible? How to trap animals, how to fish? The food would be plenty all around them but... Some of it comes with claws, and teeth, and very little fear of humans.
They would arrive at the end of summer, the beginning of fall, if the trip went well at sea. The ships would not stick around long. The voyage back had to be started on time so they would be at least halfway back to Europe before the weather got rough(er). The sailors and crew of the ships might never have seen winter in Canada or summer in Australia. Unless they were somehow left behind. The convicts would have no idea what was coming. Yes, Europe gets snow in winter. They don't get winter like Canada, winter was even harder then, with more snow and cold. Most of those early people to arrive in Canada and Australia had no chance at all.
At first, if they knew how to forage, they might have thought they were lucky... so much food right there for the picking. After starving in Europe now they had plenty. Could any of them build a fire? How would city dwellers in this time know to build a fire, without matches, or dry wood, or kindling, or rocks to get a spark.
You get the idea, more or less. Those people were not settlers, they were abandoned. Could they work together? Would they work together?
Imagine yourself left on the shore without technology, tools, friends... How many of them died right there, on the shore, just overwhelmed. But they were used to struggling, so I don't think many would have given up so quickly or completely. Those survivors, those few, are the real early settlers. They didn't know it at the time.
