The WW1 designation of Coastal Artillery Corps was created in 1901 when the US Army Artillery was divided into two divisions, 126 Companies of Heavy Artillery and 30 Companies of Light (Field) Artillery.  This was necessitated by the difference in training required to man heavy guns verses training for the quicker movements of light artillery (4 to 6 lb.) field guns.  The Heavy Artillery (8 lb.
or greater) was named the Coastal Artillery Corps and played a major roll in World War 1 when the War stagnated into entrenched positions on the front lines.

Initial involvement of the CAC was with large caliber guns, stationary mounted, along the coastal areas and foreign outposts with forts or fortified gun outposts.  We were not prepared for the large scale troop movements, and as the Unite States entered the fighting in Europe, they initially used French or British made weapons.

80% of the men who lost their lives on the battlefields, fell to artillery fire.

The evolution of warfare, specifically the use of aerial bombing and heavy tanks lead to the CAC being deactivated during WWII, and officially abolished in 1950.

William Wirt Morea, Coastal Artillery Corps, Lake County, Indiana

“While I was with Co. A., Ammunition Train, 1st Div., I was in practically every place in and around the war zone.  In order to mention all, I would need a war map of France.  I was with the 28th Infantry, 1st Div., which was the first American army outfit across into Germany on December 13, 7:30 a.m.  I was also with the H Co. that was in the 2nd Battalion.  I believe I'm one of the first boys of Lake County to cross the Rhine.  After being chosen for the Composite Army, Co. B., I traveled in every parade they took part in and return with the “General Pershing Guard of Honor” as we were called

Paul Vernon Wycoff, Coastal Artillery Corps, Ripley County, Indiana

“Fired presidential salute of 21 guns at Ft. Hamilton on Dec. 9, 1918 as President Wilson’s ship, the George Washington, sailed out of the harbor for France.  Was Sergeant of the Guards and fired reveille guns in salute as the convoy passed.”The 38th Coastal Artillery Corps was welcomed to New York when arriving from Newport News, being mistaken for overseas troops. They were in full overseas equipment as they expected to sail for France on November 11.

The two-day trip from Newport to New York was full of peril from floating mines.  The soldiers wore life belts the entire time. They reached New York in time to march in the Thanksgiving Day parade.

Longest range Field Gun, WW 1





US Official Photo, America's War For Humanity


"The longest-range field gun in the world, produced by the Ordnance department, US Army, for service in France, though the hostilities ceased before they reached General Pershing. More than a hundred of these guns are said to have been prepared for shipping to France, and their range and power would probably have an astonished the Germans, as did the great naval guns mounted on railway cars and manned by American seamen, that did such effective work in the closing days of the conflict."
