 Cumming went ashore under a flag of truce to meet with the town 's governor and demand the handing over of the merchant ships within three hours . The governor refused to comply but the Russian troops left the town shortly afterwards and the governor stated that , whilst he could not order them out of the harbour , Cumming and Key would be permitted to enter the harbour to take them . They proceeded to do so , finding themselves in control of the entire town of 10 @,@ 000 inhabitants with just 110 men , and took out the eight merchant vessels without firing a shot . The ships were sent with prize crews to the Prussian port of Memel . Cumming and Conflict also saw service at the port of Riga in this period and from 15 April to 22 May were responsible for boarding 19 vessels .
