The pre-Colombian history of the New World can be divided into few periods, as we are talking about a very long period from the initial migrations until the contact with the Europeans.
For the first few thousand years after the migrations from Asia to the Americas too place, the people were mostly living a hunter-gatherer life. They were settled in one place, but instead they moved from one place to another in order to be able to get enough food.
Around 2,000 BC we have the first signs of the development of civilizations. The people started to practice agriculture, and that enabled them to settle as they had constant food source. Because of that, they had more time, thus they started to create pottery, later metals. They started to develop cities, construct infrastructure, build empires, get engaged into science.
Some of the civilization that are the most marking are the Mississippian, Mayan, Olmec, Muisca, Aztec, Inca, Nazca. The ones that existed when the Europeans arrived were all destroyed, and only ancient monuments and buildings witness for their existence.
The Titanic of 1912, that was the day you fell.
Below the ocean floor everyone left alone to mourn.
Lusitania sunk in fifteen 761 survived, but too many to leave.
Both caused tragic deaths and people were still trying to catch their breaths.
Alone and desperate three years apart, causing all families sobs and great tears.
So as we learn with sadness in the air, a tragedy like this cannot be fair.
We must cherish everything we experience including the night that everything was serious.
Hope this helps
One distinction of the american infantry during the revolutionary war era was its use of Volley Fire.
Volley Fire is a military tactice developed with the advent of rifles and guns in the 16-17th Century.
In this tactic, a line of riflemen fire together and while they reload their weapons, another line of soldiers fire their weapons.
This is done to ensure constant firing, to make up for lost time in reloading and make up for missed shots.
The aim is to consistently be on the offensive.
It is most closely associated with the Dutch forces but was used by American forces against the British.
