In late 1826, the retired Colonel of the French army Constantin Denis Bourbaki, after getting permission from the Greek Government in Nafplio, formed a force battalion of 800-1000 men, using his own money but also an amount that was offered by philhellenic clubs of Europe. During the last days of 1826, the battalion landed in Loutraki to strengthen Georgios Karaiskakis army, but after government orders they moved to Eleusina to help Vasos Mavrovouniotis. A few days later, Panagiotakis Notaras arrived there as well, with a force of 1200 men. From Eleusina, Vourvachis and the two other chieftains, with united forces moved to Menidi, where on the 22nd of January prevailed in battle against the Ottomans. On the 26th of January, the combined force of approximately 3500 men camped in Kamatero.
Battle
The battle helped to distract Reshid Pasha's forces from engaging the armies of British generalThomas Gordon while they were completing their defensive fortifications on the hill of Munychia. On 27 January 1827, 2000 Ottoman foot soldiers and 600 horsemen, covered by artillery, attacked under the command of Reshid Pasha against the Greeks, who had split their forces in two. Vourvachis had lined his men onthe field, while Mavrovouniotis and Notaras held positions at the foot of the adjacent mountain, a third of a mile afar. More specifically, the artillery of Reshid Pasha attacked Mavrovouniotis and Notaras, while at the same time the infantry and cavalry of the Ottomans attacked the forces of Vourvachis on the field, who formed the vanguard. Despite the resistance of Vourvachis and his men, they were defeated, especially because of the Ottoman cavalry. The forces of Mavrovouniotis and Notaras were defeated as well and were forced to a disorderly retreat, most of them fleeing to Salamis Island, while the Ottomans chased them.
The battle ended in a crushing defeat of the Greek forces. From the rebels’ side 300–350 fighters were killed, including two French philhellene officers, the surgeon of the army and Dionysios Vourvachis, the head of whom was cut off and sent by Reshid Pasha as loot to the sultanMahmud II. According to Trikoupis, the eve of the battle there was disagreement between the leaders of the Greek army about the tactics that they should follow. Trikoupis blames Vourvachis, while Makriyannis believes that Mavrovouniotis is responsible, arguing that placing the troops in such a weak position was his initiative. Moreover, he expresses his doubts about the fighting abilities of the men that Vourvachis had enlisted.
