Fort Cape Disappointment was established in 1862 during the American Civil War.  Fortifications existed here from that date to protect the northern approaches to the mouth of the Columbia River from possible attacks by Confederate raiders or foreign fleets. The Fort was renamed Fort Canby on January 28, 1875, for General Edward R.S. Canby, who was killed in the Modoc Indian Wars. Three defensive earthwork batteries were constructed at Fort Canby. Lighthouse Battery (West Battery) is at the west point of the Cape, Center Battery is at the mid-point of the Cape, and East Battery is at the point on the Cape that overlooks the entrance into Baker’s Bay.

The highlight of Lighthouse Battery was the 15-inch smoothbore Rodman. By 1863, it was installed on the north side of the Cape Disappointment lighthouse overlooking the entrance to the Columbia River.

Nicknamed “Old Betsy,” it was the largest and best-known gun used at Fort Canby during the Civil War period. “Old Betsy” weighed 50,000 pounds. The projectile for the gun weighed 315 pounds and could be shot as far as two miles. It took seven men a minute and ten seconds to load the gun.

  However, there was a problem with “Old Betsy” and her location. When the gun was fired, the concussion would crack the windows of the lighthouse. This angered the head lighthouse keeper, so he sent a letter to the Secretary of War demanding the Army stop firing the gun. Orders to the Commanding Officer at Fort Canby stated the gun, “…should not be fired again because when pointed in certain directions it endangers the glass in the lighthouse.” The Army’s solution was to move it in 1893 to Center Battery where it could safely be fired.  The gun was mounted on granite blocks, the remains of those blocks can still be seen near Battery Harvey Allen at the Lewis and Clark Interpretive Center.
