Mr. Millet then goes on to tell how General Greene persuaded one of Aguinaldo's generals (Noriel) to evacuate certain trenches so he (Greene) could occupy them, "with a condition attached that General Greene must give a written receipt for the entrenchments." This condition, Mr. Millet says, was imposed by "the astute leader" (Aguinaldo). General Greene's "cleverness" consisted in purposely failing and omitting to give the receipt, which Mr. Millet says "looked very much like a bargain concluded over a signature, and was a little more formal than General Greene thought advisable." The key to this sorry business may be found in the first paragraph of General Merritt's instructions to all his generals at the time: No rupture with insurgents. This is imperative. Can ask insurgent generals or Aguinaldo for permission to occupy trenches, but if refused not to use force. [119] "I am quite unable to explain," says Mr. Millet (p. 61), "why we did not in the very beginning make them understand that we were masters of the situation, and that they must come strictly under our authority." The obvious reason was that a war of conquest to subjugate a remote people struggling to be free from the yoke of alien domination was sure to be more or less unpopular with many of the sovereign voters of a republic, and more or less dangerous therefore, like all unpopular wars, to the tenure of office of the party in power. So that in entering upon a war for conquest, a republic must "play politics," using the military arm of the government for the twofold purpose of crushing opposition and proving that there is none.
