This map and battle plan immortalized what came to be known as the Battle of Bunker Hill. The alphabetic key identifies British regiments and ships and narrates their actions. The plan also shows earthworks held by the Colonial troops. This detailed plan was published in London only five days after news of the battle itself reached England. Given the haste with which it was prepared, its geographic vagueness in the rendering of Charlestown is less surprising than its overall accuracy and detail.
