The crisis at Gosport had reached its zenith by the morning of April 20, 1861. Flag Officer Charles Stewart McCauley appeared to have given up all hope of saving or defending Gosport Navy Yard. Early that morning, he learned that militia troops had seized Fort Norfolk and an extremely useful magazine filled more than 250,000 pounds of gunpowder. Therefore, McCauley believed he had no choice but to destroy the shipyard so that it would not fall into the hands of the Virginians.
In spring 1862, Union general George Brinton McClellan had assembled a very powerful army around Washington, D.C. The Union had already recently achieved several major victories along the Mississippi River and its tributaries, as well as they had captured the North Carolina Sounds. McClellan’s army was poised and ready to strike at the Confederate capital at Richmond, Virginia. General McClellan, often called ‘Young Napoleon’ or ‘Little Mac,’ wanted nothing to do with a march overland toward Richmond.
This path was blocked by General Joseph E. ‘Joe’ Johnston’s 45,000-strong army defending Manassas. In an effort to flank and isolate Johnston’s army away from Richmond, McClellan conceived the Urbanna Plan to move his army to the Rappahannock River at Urbanna, Virginia, and then strike directly at Richmond. Before the Union general could implement his campaign, Joe Johnston abandoned his Manassas defenses beginning March 6, 1862, and fell back to Fredericksburg. McClellan quickly offered a secondary amphibious operation to strike at Richmond by way of the Virginia Peninsula.Read more
Last month, we were able to complete one of the last major steps in the conservation of USS Monitor’s two XI-Inch Dahlgren shell guns: boring concretion out of the barrels. Material Culture Specialist Hannah recently showed off what we found in this process (coal is, indeed, cool), but why clean the gun bores to begin with? And how do you actually go about doing that, anyway?
The ‘why’ has a few pieces to it. There are benefits to our archaeological knowledge of the wreck, but our primary concern was keeping the guns in good condition. Monitor’s guns are made of iron, and specifically are made of grey cast iron. Grey cast iron is not 100% pure iron; it contains about 4% carbon, and that carbon exists as flakes of graphite locked in by the metal surrounding it – picture little shavings of pencil lead and you won’t be that far off.Read more
Today marks a somber day in the history of the United States of America. 155 years ago, our country suffered its, to this day unbeaten, greatest maritime disaster by loss of life. If that seems surprising to you, then you aren’t alone. It is, unfortunately, a chapter of our collective maritime heritage that has been largely forgotten. Why? Because it happened at the end of April in 1865.
If you’re familiar with the history of the American Civil War, then you no doubt know that April of 1865 was one of the most formative years of our Union. It was a month that saw union forces march into Richmond and high-profile surrenders that led to the end of the war. It was the month in which Abraham Lincoln was shot and killed by actor and confederate sympathizer John Wilkes Booth. The day immediately before the disaster, Booth was cornered in Bowling Green, VA, and slain by Sergeant Boston Corbett of the 16th New York Cavalry.Read more
Tensions were rising throughout the South during the first week of April 1861. While the Upper South had yet to join the Confederacy, the Lincoln administration was alert to the threatening war clouds and the possibility of states, like Virginia, leaving the Union. Secretary of the Navy Gideon Welles recognized that Gosport Navy Yard and the steam screw frigate USS Merrimack were tempting targets for pro-secessionist Virginians. Accordingly, on April 10,1861, Welles advised Gosport Navy Yard commandant Flag Officer Charles Stewart McCauley that he must show great vigilance in protecting the yard. He stated that it was important that one of the US Navy’s most modern warships, Merrimack, be repaired and moved to another navy yard. Welles added that McCauley was to do nothing to upset the Virginians and to use his best judgment in discharging his duties to protect Gosport. Welles concluded, it is “desirable that there should be no steps taken to give needless alarm.”
Merrimack Readies for Sea
Gosport’s commandant responded by telegram on April 11, stating that it would take a month to revitalize Merrimack’s dismantled engines. Welles was shocked by McCauley’s reply, calling the yard commandant “feeble and incompetent for the crisis.” He sent US Navy’s chief engineer, Benjamin Franklin Isherwood, to Gosport to prepare Merrimack for sea. Isherwood estimated that it would take him a week to rework the ship’s engines. Commander James Alden was ordered to accompany Isherwood and assume command of the frigate. They arrived at Gosport Navy Yard on April 14, 1861. Isherwood immediately set to work restoring Merrimack’s machinery.Read more
