Orders were now issued for an advance of the army on Jalapa, General David E. Twiggs, with the Second Division of regulars, to lead the movement on the 8th, two brigades of volunteers to follow. On the 9th Patterson's division moved, but, for want of transportation, Quitman's brigade, Colonel James H. Thomas, Tennessee mounted regiment, Worth's division, and the siege train were left at Vera Cruz. General Twiggs was notified by General Scott that he had information that General Santa Anna had arrived at Jalapa with six thousand troops, though he [General Scott] regarded the numbers as exaggerated. General Twiggs, on receipt of General Scott's notice, replied that the Mexicans would doubtless endeavor to hold the pass of Cerro Gordo between the National Bridge and Jalapa. Through Mexican sources he had information rating Santa Anna's force at from two thousand to thirteen thousand, and that he expected to arrive on the evening of the 11th at Plan del Rio, the point where the Mexican advance was posted.
General Scott had received information that Generals Patterson and Twiggs had met a strong force of the enemy at Plan del Rio. Worth's division was ordered forward, and Quitman directed to follow in twenty-four hours. General Scott himself now moved out under a cavalry escort.

General Santa Anna had arrived at Cerro Gordo on April 9th. General Scott, on his arrival, ordered (on the morning of the 11th) reconnoissances to be made on the Mexican left by Captain Robert E. Lee, which were resumed on the 16th. These reconnoissances determined the order of attack, which was to make a demonstration with the commands of Generals Pillow and Shields on the Mexican right, and press the mass of the army on their right. This movement being successful, the enemy's communications would be cut off. In the meantime the Mexicans were busily engaged in greatly strengthening their positions.
General Scott had not intended to attack the enemy in the absence of Worth's division, which had not yet arrived. A movement of Lieutenant Franklin Gardner, re-enforced later by the mounted rifles under Major Edwin Vose Sumner and a battalion of the First Artillery under Lieutenant-Colonel Childs, to occupy a position near the base of the Atalaya, provoked a sharp conflict. General Santa Anna, being at the front, ordered re-enforcements. Colonel Thomas Childs withdrew, having advanced under a misapprehension. The American loss was ninety-seven, killed and wounded. General Scott returned to Plan del Rio and issued the following order:
"Headquarters of the Army,
"Plan del Rio, April 17, 1847.
"General Orders No. 111.
