Correct!  Martinez seized the Iphigenia but released the vessel in part
because its written instructions (carried by ships) were in Portuguese,
“of which no one in our ship is master.”   Sailing under the false flag
of Portugal, it was part of a British trader, John Meares, scheme to
escape paying taxes while circumventing his British identity.

A Secondary Question:
Considering Cascadia is from 3,500′ elevation to Sea Level … from Kodiak to San Francisco Bay, what was the likely number of Indigenous People in Cascadia in 1492?
This 300 years before Vancouver followed Martinez (by 4 years) and settled this dispute that almost put Spain and England at War?

1)        25,000
2)      250,000
3)  2,500,000

with perhaps 50% of this Indigenous Population within Salish and Puget Sound?
