Aguinaldo had declared himself a dictator and the Philippines independent.

To have recognized him in his civil capacity, to have dealt with him in his civil capacity, would have meant a recognition of his government by the military commander in the field--a thing impossible and unlawful.

Officers of the United States forces are not empowered to recognize governments; that function is reserved to the President of the United States; and in this case he, in his orders to the Secretary of War, dated May 19, copies of which were forwarded to General Merritt for his guidance, informed him that the army of occupation was sent to the Philippines 'for the twofold purpose of completing the reduction of the Spanish power in that quarter and of giving order and security to the islands while in the possession of the United States.' These instructions contemplated the establishment of a military government in the archipelago by military officials of the United States.

* * * * * "It has been claimed that Aguinaldo and his followers received the impression at this time from their conversation with American officers that the United States would undoubtedly recognize the independence of the Philippines, and that the cooperation of the insurgents was due to this impression.

There was no cooperation.

That he attempted in vain to secure the surrender of Manila to himself was not cooperation.
