Four 8 inch, rifled Dahlgrens at Patriots Point (Cooper River bridge in background).

As visitors pull into the parking lot at Patriots Point, they may notice four large cannons on the shore pointed at the USS Yorktown. Some astute observers will recognize them as Dahlgren guns.

The guns take their name from a career Naval officer, Rear Admiral John Dahlgren, who was especially qualified in the development of  ordnance for the United States Navy. His gun design bore his name and had the distinctive  shape of a soda bottle. The four Dahlgren guns at Patriots Point were made at Builders Foundry in Providence, Rhode Island in 1863. Their original numbers were No. 63, 64, 67 and 69. They were originally 11 inch Dahlgrens  and weighted around 15,750 pounds (each is slightly different).  These 11 inch Dahlgrens could fire a shot that weighted 170 pounds.

The Patriots Point Dahlgrens were pivot guns, so they would have been deployed aboard ships such as New Ironsides and Kearsage.  We are still researching the National Archives to find their Civil War service history. Carriage guns were placed in the new ironclad monitors like the Monitor (2 11 inch Dahlgrens) and the Keokuk (2 11 inch Dahlgrens).The Keokuk led the attack on Fort Sumter in April 1863 and was badly damaged. She sunk off of Morris Island and the Confederates were successful in raising one of her guns, which today is on display at the Battery in downtown Charleston, South Carolina.

The four Patriots Point Dahlgrens were converted in 1879/1880 to 8 inch rifled Dahlgrens by reaming out the bore to 13 inches and then sleeving them down to 8 inches. This increased their weights from around 15, 750 lbs to 17,330 lbs.

USS Lancaster

The Patriots Point Dahlgrens were assigned to the USS Lancaster in 1881. She was the flagship of the European Squadron from 1881 to 1894 and was at Alexandria, Egypt during riots in 1882 and she traveled to Russia with diplomats and dignitaries for the coronation of Tsar Alexander III in May 1883. The Patriots Point Dahlgren’s were removed from the USS Lancaster in 1895 at the Charleston Navy Yard and they served as gate ornaments until the base’s closure in 1995. They were transferred to Patriots Point Naval and Maritime Museum where they are on display today.

  1. Butch, I enjoy the blog & have subscribed since 10/6 of last year, where I learned about it at the Yorktown Assn reunion of which I am a member. I came across this link: http://www.youtube.com/watch?v=fgt8PMoRGG8&featur where Jimmy Doolittle’s grandaughter, Jonna, speaks, without teleprompters, about her grandfather & would he ever be proud of her. She wrote a book, called “Calculated Risk” which is a good read. Thought it might be something you might want to use on April 18th, which will be the 69th anniversary of the raid. The ending is especially great, and certainly a tribute to the work that you do with your blog. Thanks..
