Lawrence was a schooner and the first privateer to be licensed out of the port of Halifax, Nova Scotia.
The ship was under the command of Captain Joseph Rouse with Robison Fort as first lieutenant, Andrew Gardner as mate.
The ship was named after Nova Scotia Governor Charles Lawrence.
On 21 April the Lawrence was battered and the only craft that was available to General James Murray.
The schooner was sent eastward to hasten Lord Colville's fleet when it arrived in the river.
