Aguinaldo himself made the charge in his "Reseña Verídica" [18]
in the following words:--

"In this interview Consul Pratt told me that because the Spaniards
had not complied with the agreement of Biac-na-bató, the Filipinos had
a right to renew their interrupted revolution and advised me to take
up arms anew against Spain, assuring me that America would give the
Filipinos the greatest advantages (mayores ventajas). Then I asked
the Consul what advantages the United States would concede to the
Philippines, suggesting, when I had the proper opening, the propriety
of making an agreement in writing, to which the Consul answered that
he would report, by telegraph, on the subject to Mr. Dewey, who was
the chief of the expedition against the Philippines, and who had
ample powers from President McKinley.

"On the following day, between 10 and 12 in the morning, we again took
up the matter, Consul Pratt saying that the admiral had answered my
inquiry by saying that the United States would at least recognize the
independence of the Philippine government under a naval protectorate,
but that there was no necessity to put it in writing, as the words
of the admiral and the American consul were sacred and would be
fulfilled, not being like those of the Spaniards, and finally, that
the Government of North America was a very honourable Government,
a very just and very powerful one." [19]

"General Aguinaldo gone my instance Hongkong arrange with Dewey
