10 INTRODUCTION. 
by simply appearing on the coast he could frighten the viceroy into 
submission, and that by harassing the petty villages along the shore, 
he could possess himself of the castles of Callao. However, on the 
28th, as we have seen, he embarked; on the 29th, the fleet anchored

“ Remember, that you are the conquerors of Valdivia: and do not
