Next in line on the trail is The Korean War bust. The monument is of a man wrapped in a standard issue blanket, reflecting the cold temperatures that most soldiers experienced while fighting in Korea. This conflict was fought to diffuse a Communist spread into Asia. After World War II, Russia became the next major threat with their attempt at spreading their influence into Asia. When peace was declared after World War II, Korea was split in half, with the Socialists in North Korea attempting to invade South Korea. The United Nations intervened, defending the infamous 38th Parallel from the North Koreans, who were backed by the communist forces of China and Russia. The UN used both swift infantry raids and bombing runs in order to force back the North Koreans from the demilitarized zone, but in 1953 a stalemate was declared. UN forces still occupy the 38th parallel to this day.

Continuing on the trail you come to the World War II busts standing side by side. The two busts, one of whom is an infantryman and the other being a seaman, both visualize the struggle and hardship that all generations faced while fighting against the rising Nazi threat. In 1939 the allied powers, with the exception of the United States, declared war on a vicious Nazi Germany, whose borders had violently made their way into Poland and Austria. Japan, who had allied themselves with Germany along with Italy, soon attacked Pearl Harbor, provoking the United States to defend itself and come to the aid of the Allied forces. The war raged on both in Europe and in the Pacific, lasting a total of six years before ending in 1945 with the death of Nazi Germany’s dictator, Adolf Hitler, and finally with the bombing of Japan through use of the first nuclear weapons.

The next two busts along the trail are dedicated to the servicemen of the First World War, also known as “the Great War.” The monument features two busts: an infantryman and a pilot, representing the two major fronts of the conflict. World War I was the tragic result of numerous alliances of rival European countries being provoked into war by the assassination of Archduke Franz Ferdinand of Austria-Hungary. The conflict is noted for the evolution of immensely lethal weapon technologies such as poison gas, tanks and new aerial warfare through the use of airplanes. Most of the war was fought from the trenches of France and along the RussianGerman border between the Allied and Central powers. In 1918 American forces entered the conflict and the trenches, and with the aid of these additional troops the Central powers were defeated.

The next monument on the trail is in honor of those who served in the Spanish American War. This war fought for control over Cuba and the Philippines out of fear of a Spanish invasion of the United States and to create a hold on South America. The war ignited after the sinking of the battleship Maine, and with the help of the media, the United States gave Spain the ultimatum to either leave Latin America or face retaliation. Spain and the United States declared war in 1898, beginning ten weeks of one sided victories for the Americans, ultimately annihilating the Spanish troops in South America. Once peace had been declared, the United States gained temporary control over Cuba, as well as indefinite control over Guam, Puerto Rico and the Philippines. The serviceman resembles a member of the 1st United States Volunteer Cavalry, a unit later led by future president Theodore Roosevelt that was nicknamed “The Rough Riders”.

As you continue on the trail, you will come upon the bust dedicated to the American Civil War. The bust is of an old Union serviceman, one of many who fought during the bloodiest war fought on American soil. The serviceman wears a signature forage cap, a fatigue hat that became the common headgear for Union soldiers. This gruesome conflict began over whether each individual state should be allowed to make their own rules or if they should follow regulation from the federal government. The southern states wanted to be able to create their own laws, and forcibly seceded from the Union in 1861. After the Confederate states attacked Fort Sumter in Charleston, South Carolina, war erupted between the Confederacy and the Union, forcing many Americans to face one another on the battle field until General Lee surrendered his troops in 1865.
