On March 15, 44 BCE, Julius Caesar, dictator of Rome, was stabbed to death by about 40 senators. Julius Caesar was assassinated by about 40 Roman senators on the "ides of March" (March 15) 44 BCE. Caesar's death resulted in a long series of civil wars that ended in the death of the Roman Republic and the birth of the Roman Empire.
A couple of weeks before the Battle of New Orleans, the U.S. and British governments had negotiated and signed a peace treaty that put an effective end to the war between the two countries. Given that news from Europe took about a month to reach the U.S., both the U.S. soldiers led by General Andrew Jackson and the Red Coats led by General Sir Edward Pakenham was a pointless confrontation. A few weeks after the resounding U.S. victory (only 13 men were killed on the U.S. side and 285 on the British side), Jackson and his men got news of the peace treaty signed before their feat of arms.
The technology, logistics, and communication of the north that allowed them to defeat the south is because of their skill of having to manufacture supplies and weapons that they need for the war. They were able to create more weapons and be able to hire more soldiers.
Hope this helped :)
Have a great day
The CCC (Civilian Conservation Corps) employed about 30,000+ people, who helped build things like dams, roads, bridges, fences, signage, and campgrounds in South Carolina.
