Alexander’s troops had much protection on their head and chest. This could be because their troops were more valuable and not as replaceable as the Romans who also had protective armor but not as heavy. The Romans carried more light armor for better mobility. To the Romans speed was more important than defense. They did not fight like a unit as much as the Alexandrians did, it was more stagnant and vicious.
Depends on how you look at it.. They were desperate and had to stop the British from gaining support. But it wasn't confirmed that It was carrying weapons, there were civilians on it so theres good reasoning why they sunk it. The Germans did not let civilian casualties get in their way really as seen with their bombing of cities and use of chemical warfare.
The people in the colonies are lazy, it's that simple. Colonies thought if they captured someone who is considered a lower class the them, they could use them as property, and work labores.
