Administrative / biographical background
The source was a Spanish derrotero captured by Capt. Sharpe in the 'Trinity' (with Ringrose on board) from the Spanish ship 'Rosario' off modern Ecuador on 29 July 1681. Cabo de San Lucas was the departure point for the Acapulco-bound Manila Galleon, and therefore a focal point for pirates waiting for the galleon.
