Putnam county was named in honor of Israel Putnam [1718-1790]. During the French and Indian War, he served with Rogers’ Rangers. Later he was captured by Indians but was spared from being burned at the stake by the last-minute intervention of a French officer. In 1759, Putnam participated in the attack on Fort Ticonderoga and later at Montreal. In 1762, he survived a shipwreck during a campaign against the Spanish in Havana and later served at Detroit during Pontiac's Rebellion. In June 1775, as a major general in the Continental Army during the Revolutionary War, Putnam offered distinguished service at the Battle of Bunker Hill, planned the fortifications for Breed’s Hill and later fought in the battle itself.
