Battle Rock - Port Orford, Oregon - American Guide Series on Waymarking.com

From the guidebook:
The region about PORT ORFORD, 165.6 m. (56 alt., 300 pop.), was sighted in 1792 by Capt. George Vancouver, who named it for the Earl of Orford. This rambling village on a bluff has wide view of the Pacific.
Near the village is BATTLE ROCK where nine gold hunters were landed in June 1851 with supplies and a cannon by Capt. William Tichenor of the Seagull. Shortly thereafter the Coquilles attacted the invaders who were able to drive them off and flee to the settlements along the Umpqua. Captain Tichenor returned with 69 more men who established a camp they called Port Orford.

Text of history sign at Battle Rock:
Battle Rock City Park has been dedicated in memory of the ancient people (Dene Tsut Dah) and the pioneer founders of this townsite. In 1850, the U.S. Congress passed the Oregon Donation Land Act. This act allowed white settlers to file claims on Indian land in western Oregon although no Indian nation had signed a single treaty. Capt. William Tichenor of the Steamship Sea Gull landed nine men on June 9, 1851, for the purpose of establishing a white settlement. This resulted in deadly conflict between the two cultures. For two weeks the nine were besieged on the island now called Battle Rock. Under cover of darkness, the party escapted north to Umpqua City. In July, Capt. Tichenor again arrived with a well-armed party of seventy men and established the settlement now called Port Orford. Later, Tichenor became a permanent resident after his retirement from the sea.
