Which river did the British decide use for travel on their way to Concord

Charles River

They took separate routes in case one of them was captured: Dawes left the city via the Boston Neck peninsula and Revere crossed the Charles River to Charlestown by boat. As the two couriers made their way, Patriots in Charlestown waited for a signal from Boston informing them of the British troop movement.

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)
