Martha Alderson, M.A.


  • Robert Stockton, by now a commodore, sails to Texas with secret orders from newly elected President Polk — convince President of the Republic of Texas to provoke a war with Mexico over boundary issues. Polk, unwilling to risk the good favor of his European allies, refuses to get involved. He wants the deed done without the order coming directly from him
  • President Jones of the Republic of Texas refuses Robert
  • Still under secret orders from Polk, Robert proceeds to the Pacific to relieve Commodore Sloat as supreme commander of the U.S. Naval forces in the Pacific. Once war with Mexico is declared, Robert is to take possession of California and establish a government un the American flag
  • Robert is 50 years old (average age in those days was 42 years old)
  • Nine children
  • Famously wealthy
  • Incredibly powerful
  • Robert wanted to redeem himself over the explosion of the cannon he built on the Princeton. He personally knew the men of power who died

President Polk elected

Polk tries to buy California from Mexico—Mexico won’t sell

A declaration of war by President Polk would not be viewed favorably in Europe

Texas is a nation and wants to be annexed into the Untied Sates.

Many opposed annexation because Texas will be added as slave state and throw off the delicate balance between free sates and slave states—tension in the country is building

Polk wants Robert to help Texas place itself in an attitude of active hostilities towards Mexico over the Rio Grande boarder.

Polk sends Robert to California by sea, John C. Fremont overland the northern route, and Kearny overland the southern route, all with the same secret orders—take California for the U.S.
