The left section of the battery shared in an expedition to Florida in September and October, 1862, and was active at Fort Finnegan.

Following this the battery was ordered to Folly Island and for nine months it formed part of the reserve under General Quincy Adams Gillmore.

[4] On April 18, 1864, the battery embarked for Fort Monroe from where it proceeded to Gloucester Point and on May 4, it joined General Benjamin Butler's forces at Bermuda Hundred.

[4] It was actively engaged at Chester Station on the Richmond and Petersburg turnpike and at Proctor's Creek, losing two killed and ten wounded among the former being Lieutenant George Metcalfe.

But on April 3, 1865, the Confederates abandoned their defences and the battery entered Richmond with the XXV Corps, where they received news of Lee's surrender.
