 Arriving at Port Townsend, Washington, on 30 April, Yorktown put to sea on 13 May, arriving at Iliuliuk, Unalaska, one week later. Coaling there, the gunboat skirted the ice floes near the seal rookeries of the Pribilof Islands, reconnoitering the vicinity for sealers. Assisted by a revenue cutter, Yorktown guarded the passes to the Bering Sea. The crews of the patrolling American ships lacked fresh provisions but carried on in spite of the hardships imposed by both diet and climate. Fresh fish, however, proved abundant. Codfish was the staple with an occasional gourmet treat of salmon.
