Meanwhile, the Greek 7th division had been fighting on the far east flank. On 19 June it successfully captured the saddle of Karakoli, however on 20 June even though it faced no resistance it advanced slowly toward Nigrita which it captured. A Bulgarian force consisting of regimental staff and one battalion was advancing aggressively toward Karakoli. It was encircled and surrendered with 10 officers and 1500 men. On 21 June the division continued its slow advance. Even though it was informed of the Bulgarian defeat and retreat over Orliako bridge, its columns advanced too slowly to block the Bulgarians. The division was heavily criticized for its unacceptable failure.
