In Senate Document 196, 56th Congress, 1st Session, dated February 26, 1900, transmitted by Secretary of the Navy Long, in response to a Senate resolution, may be found a report of a tour of observation through the half of Luzon Island which lies north of Manila and the Pasig River, made between October 8 and November 20, 1898,--note the dates, for the Paris Peace Conference began October 1st and ended December 10th,--by Paymaster W. B. Wilcox and Naval Cadet L. R. Sargent. This report was submitted by them to Admiral Dewey under date of November 23, 1898, and by him forwarded to the Navy Department for its information, with the comment that it "in my opinion contains the most complete and reliable information obtainable in regard to the present state of the northern part of Luzon Island." The Admiral's endorsement was not sent to the Senate along with the report. It appears in a book afterwards published by Paymaster Wilcox in 1901, entitled Through Luzon on Highways and Byways. The book is merely an elaboration of the report, and reproduces most of the report, if not all of it, verbatim. The book of Paymaster Wilcox may be treated as, practically, official, for historical purposes. The preface recites that in October, 1898, American control was effective only in Manila and Cavite, that the insurgents, under Aguinaldo, who had proclaimed himself President of the whole Archipelago, immediately after Dewey's victory, were in supposedly complete possession of every part of the Island outside of these two cities, that their lines were so close to the outposts of our army that their people could at times converse with our soldiers, and that General Otis's authority did not extend much beyond a three-mile radius from the centre of Manila, while Admiral Dewey held and operated the navy-yard at Cavite. "Even the country between Manila and Cavite was in the hands of Aguinaldo, so much so that our officers had been refused permission to land at any intermediate point by water, and were prohibited from traversing the distance by road." Wilcox and Sargent procured leave of absence from Admiral Dewey to make their trip. They went first to Malolos, but failed to get anything in the way of safe-conduct from Aguinaldo. He is described, however, as of "great force of character * * * and he dominates all around him with a power that seems peculiar to himself." Wilcox had seen him before at Cavite. "He adroitly read between the lines that the Government of the United States did not then, nor would it at any future time, recognize his authority," says the writer.
