Source-derived summary

CSS Ivy was a sidewheel steamer and privateer purchased by Commodore Lawrence Rousseau for service with the Confederate States Navy, and chosen by Commodore George Hollins for his Mosquito Fleet. The Mosquito Fleet was a group of riverboats converted to gunboats, and used to defend the Mississippi River in the area of New Orleans during the American Civil War.

Equipped with a powerful rifled 32-pounder, Ivy fought with the Mosquito Fleet at the Confederate victory of the Battle of the Head of Passes and their defeat at the Battle of Island Number 10. Subsequently, trapped in the Yazoo River, Ivy was destroyed to prevent her capture by the Union in May 1863.

Description

Ivy was 191 feet (58.2 m) long overall, had a beam of 28 feet (8.5 m) and a draft of 9 feet (2.7 m). Her two side paddle wheels were powered by a large, sophisticated walking beam engine and multiple boiler propulsion system with 44 inches (112 cm) diameter cylinders on an 11 foot (3.4 m) stroke, giving a maximum speed of 12 knots (22 km/h; 14 mph). She had a complement of 60 officers and men.

As a privateer Ivy was armed with two brass 24-pounder smoothbore howitzers. As a riverboat her armament was increased to an eight-inch smoothbore mounted aft, and a 32-pounder rifled gun mounted on a forward pivot position on the bow. The conventional description of "rifled 32-pounder" is misleading, however.

Editorial analysis

Why this record matters

The phrase “steamboat” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Dec 31, 2025. The linked authority identifier is Q5014306. Authority coordinates are 32.711, -90.519. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1863.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
