According to Romaine, William Govett to Fortescue, 1st Baron Carlingford Chichester 27 September 1859, CO 305:12, no. 9686, 47, on August 11, 1859, Rear Admiral Baynes was invited to conference on the US steamer Shubrick, by Lieutenant Colonel Casey. Baynes declined the meeting on the Shubrick, but extended an invitation to Casey to come aboard his own ship, HMS Ganges.
The Shubrick is mentioned also in this despatch, in which Governor Seymour was forced to send a request to its Commander not to fire a salute, as he lacked the ability to return the compliment due to a lack of supplies.
