 The governor sent to arrest General Ronquillo on the road before he entered Manila, intending to proceed against him by law for having withdrawn the camp and army from Mindanao River without awaiting the orders he should have expected after the favorable turn of affairs.However, General Ronquillo was set at liberty on showing a private letter from the governor, which the latter had sent him separately with the first instructions, to the effect that he should return to Manila with his troops in any event, because they were needed in the islands for other purposes; and because of this letter Don Juan had determined not to await the second order.This partial withdrawal of the Spanish resulted in their opposition gaining considerable strength.
