This monument was in honor of the men of Chappaqua town of the new castle who honorably served and died for their country 1917-1919. The Great War was another name for World War I, which was a global conflict that lasted from 1914 to 1918. The United States joined the war in 1917 after Germany resumed unrestricted submarine warfare and tried to form an alliance with Mexico against the U.S.2. The war ended with the defeat of the Central Powers (Germany, Austria-Hungary, Turkey, and Bulgaria) by the Allied Powers (France, Britain, Russia, Italy, Japan, and the U.S.)1. The war had a huge impact on the world, causing millions of deaths, political upheavals, social changes, and revolutions34. The rock was a memorial for the soldiers who fought or died in the war.
You can honor those brave men by sitting, pondering how lucky we are not to have an active conflict here on our land, and then of course express solidarity by finding the geo.
