Students will examine eighteen telegrams to learn more about troop movements, battles, victories, and defeats, as well as other information communicated in telegrams in order to respond to the compelling question, “What do telegrams tell us about the Battle of Gettysburg?” The range of telegrams in this inquiry allows students to examine different perspectives on events related to the Battle of Gettysburg in 1863. The final summative assessment asks students to make an argument about how Union military leaders used telegram messages during the battle.
