Can anyone give me four HISTORICAL events from the book My Brother Sam is Dead?

Answer 1

I think you'll find what you're looking for at the first site below.
The second link is to this, one young reader's opinion:
"We talked about the third part of the novel "My Brother Sam is Dead." British soldiers torchered the town of Redding, and Sam and Tim were reunited. This book doesn't have any historical information and events, and our group said the beginning of the novel is very interesting, but the end gets boring, because the novel does not have details about the Revolutionary War, and Sam is supposed to die in the middle of the novel. I am the researcher, I researched about the author James Collier; he grew up in a writing family and his brother Christopher Collier is a historian. We were surprised that the author of the book is also a jazz musician who plays trombone."

But that doesn't seem to be true:
"After James produces the final draft Christopher gives it a final, extensive facts check before it goes to the publisher. When the brothers were writing about the decapitation of the slave Ned in My Brother Sam Is Dead, Christopher visited the site and measured distances so that every move and action would be portrayed as accurately as possible. They even used the exact words reportedly said by the British officers."

The last link is to sparknotes, the context; it has some good, historical connections. Here's a sample:
"Context
My Brother Sam is Dead begins in 1775, when the New England colonies were just beginning to join forces in rebellion against their ruler, the mighty British government. Since their founding, the colonies had paid taxes to the king of England, retained many British customs, and often followed the Anglican religion. By the time when this story takes place, the movement for independence had begun to spread through the land, gaining great following at the universities, including Yale, where the fictional character Sam Meeker is a student. The Boston Tea Party had happened, exciting the rebel Patriots and offending the Tories, New England men who remained loyal to England. The colonies were beginning to divide in their loyalty. The makeshift rebel militia, the Minutemen, rose under the leadership of George Washington and defeated the British forces in the battle of Lexington and Concord, an event Sam notes in chapter one. Even with so much pro-Patriot sentiment, Redding, Connecticut, where the Meekers live, was a Tory town. It is a historical fact that Redding inhabitants endured aggression and the stealing of their guns and cattle, partly out of wartime desperation for goods, and partly out of animosity toward the Loyalists."
