Arriving at Jersey City, they were ordered to report to Major General N. P. Banks, Commanding Department of the Gulf, and were quartered at East New York, where they remained two months, and then proceeded to New Orleans, arriving in that city on the 1st day of February, 1863.
They immediately proceeded to Baton Rouge and were assigned to the 1st Brigade, 1st Division, 19th Army Corps.
At Baton Rouge they were occupied in doing pictet duty and in protecting the city from repeated attacks of guerillal.
On the 14th of March they were among the first to approach the works of Port Hudson to co-operate with the fleet which passed those works on that memorable night.

They participated in the siege of Port Hudson, and in the assaults on the 27th of May and on the 14th of June, losing in these engagements, 88 men killed and wounded.
