Zouaves and surfboats!
From Osprey’s upcoming title, American Civil War Amphibious Tactics, by Ron Field, illustrated by Steve Noon:
Hawkins’ Zouaves At Hatteras Inlet, August 28, 1861
Elements of the 9th New York Infantry, also known as Hawkins’ Zouaves [or the New York Zouaves, Little Zouaves, and Zoo-Zoos], land via surfboats on Hatteras Inlet, North Carolina, on August 28, 1861. The first major amphibious landing of the Civil War was disrupted by gale-force winds and high surf that stove many of the boats and caused the landings to be called off, leaving 323 troops stranded on the beach overnight. Re-forming at the point where they had struggled ashore, these men spent a miserable night ashore in a driving rain. Although vulnerable to attack from the Confederate garrison at Forts Hatteras and Clark, Colonel William F. Martin, commanding the Confederate defenses in the forts, overestimated their numbers and lost the initiative, surrendering to Flag Officer Silas H. Stringham, USN, the next day.
Yup, I already have it on pre-order.
