This collection is made up of 92 letters that Louise Maxwell received from family members who served in the United States Army, Navy, and Marine Corps during World War I, including her brothers Daniel, Peter, William, John, and Joseph and her cousins Fred Gibbs and Dan Maxwell. Louise's correspondents wrote about many aspects of their service in the United States and Western Europe during and after the war; they occasionally relayed and commented on news of each other. Some mentioned conditions in training camps in the United States, where they participated in gas mask drills and other exercises. The soldiers and sailors discussed travels in England, particularly to London, during the war, and in Belgium, Germany, and the Orkney Islands after the Armistice. Joseph mentioned a plane crash in his letter of October 25, 1918, and Will referred briefly to his combat experiences. Some of the letters are addressed to the Maxwells' mother.
