Vancouver had decided to use his ships'…
June 1792 CE
On June 12, Vancouver, along with Puget and some of the crew, had sailed north from Birch Bay in Discovery’s two smaller sailing yawls.
In four days they find and chart a number of points and inlets, such as Point Roberts, Point Grey, Burrard Inlet, Howe Sound, and the Jervis Inlet.
On June 13, near Point Roberts, Chatham encounters the Sutil and Mexicana, both vessels built for exploring the newly discovered Strait of Georgia, carried out in 1792 under Dionisio Alcalá Galiano, on the Sutil, and Cayetano Valdés y Flores, on the Mexicana.
The two expeditions cooperate in surveying the complex channels between the Strait of Georgia and Queen Charlotte Strait, in the process proving the insularity of Vancouver Island.
