Since the link no longer works, I have a newspaper article from the Mountain Democrat, Placerville, Ca (1971). It is in a column called California Stageccoach Days by Vern Hammond and is entitled "Mutiny on the Bay".

Jonathan Biddy and 4 others were charged with mutiny on the USS Ewing among other charges. All were sentenced to death by hanging. Jonathan's sentence was commuted, along with 2 others, to 100 lashes and hard labor in prison. John Black was hanged from the yardarm of the Ewing. Peter Black was hanged on the USS Savannah, the flagship. They were interred on Yerba Buena Island and moved when the Bay Bridge was built 80 years later.
