Shipping products by railroad was much cheaper, and the cost of goods decreased
Explanation:
The railroad was considered the greatest American technological achievement of the nineteenth century. It served as a vital link for trade and travel that connected the eastern and western halves to the late nineteenth century in the United States.
Because railroads were very cheap transportation options, the industries had a much lower cost of production transporting their products by the railroads than by transporting in other vehicles. As the cost of production includes the cost of transportation and is a factor influencing the final price of the goods produced, the price of these goods were lower as a result of the lower transportation costs.
The best strategy was the hit and run tactics. That's called guerilla warefare. When a group/team hides in a natural environment, using their own surroundings as an advantage.
During the period that the Articles of Confederation were ratified, America was still at war with Great Britain. Because of that the Colonies were still trying to define themselves as a united country but struggling on how to do so.
