under General Eberhard Graf von Schmettow comprised the 1st Austro-Hungarian and 3rd German Cavalry Divisions. Both units were under the direct command of von Schmettow, initially the commander of only the 3rd Division. General Krafft's Alpine Corps comprised the Jäger Brigade (Brigadier General Ludwig Ritter von Tutschek) and the Bavarian Guard Regiment (Colonel Franz Ritter von Epp). Both the Central Powers and the Romanians would receive reinforcements during the battle. On 26 September, Lieutenant-Colonel Toma Popescu, a staff officer carrying messages from the 1st Army to Popovici, arrived south of the Red Tower Pass and created a makeshift force which he used against the Alpine Corps. Von Falkenhayn received the 89th Prussian Division (General Friedrich Freiherr von Lüttwitz) on 27 September. The Romanian 1st Army received the 20th Division (General David Praporgescu) also on 27 September. On 25 September, General Culcer began moving north by rail from the western Danube half of the 20th Division. On 28 September, the Romanian 2nd Army - 3 divisions strong - attacked the flank of the German 9th Army in an attempt to relieve the besieged Popovici. In its drive against von Schmettow's forces, the 2nd Army also fought against the Austro-Hungarian 71st Division (General Anton Golbach) - itself part of Curt von Morgen's I Reserve Corps - thus bringing into the fray the army which this division was a part of - the 1st Austro-Hungarian Army of General Arthur Arz von Straußenburg. The 4th Division of the 2nd Army (General Grigore Crăiniceanu) was the closest to Popovici's forces. The 4th Division was commanded by General Grigore Simionescu. The 3 divisions of the 2nd Army were the 3rd, the 4th and the 6th. On the side of the Central Powers, the XXXIX Corps alone had 35 battalions, each with 500-600 men, as well as 54 artillery batteries. The Romanian I Corps had 25 battalions, each with over 800 men, as well as 16 artillery batteries (including 2 batteries of 120 mm howitzers). Of the 54 artillery batteries fielded by the Central Powers, 13 were heavy, whilst of the 16 Romanian batteries, only 2 were heavy. Part of the Central Powers artillery came from the Alpine Corps division. The terrain and absence of roads in its area of operations prevented this division from using its artillery, and as such this was sent to reinforce the XXXIX Corps. Instead, this division used two batteries of Austro-Hungarian
