The living memorial is trees planted at the post building with markers placed near the trees in memory of veterans who died in World War I, World War II, Korea and Vietnam.
Commander Richard Wodinowich opened the ceremony with Post 1014 Color Guard of John Barton, Dan Rickert, Pat Cotton, Widinowich and Vernon Marquette.
The guest speaker for the ceremony was state Rep. Mike Dethrow. He reminded post and auxiliary members and guests to never forget the great cost of liberty. He said, "We freely enjoy our liberty, but just because it is free does not mean it came to us at no cost."
Dethrow said in the Revolutionary War 33,000 soldiers died. "In the War of 1812, 7,000 died and in the Mexican War 13,000 soldiers perished."
He gave the number of deaths for the following wars: Civil War, 110,000 Union soldiers soldiers died in combat. 94,000 confederate soldiers died in combat. Many Union and Confederate soldiers also died of disease; Spanish American War, 4,000; World War I, 53,513; World War II, 292,131; Korean War, 33,651; Vietnam War, 47,369; Gulf War, 700; War in Iraq, so far 3,000 deaths.
"A total of these figures reveals there have been over 2,800,000 American soldiers who have died over the last two centuries fighting for our country's freedom and liberty," he said.
Weeks earlier Alton Cub Scout Troop 102 had planted four oak trees on the post property.
During the dedication markers were placed near the trees symbolizing the four wars.
