Note 223 — Chapter XIV · SIR IAN’S RECALL

Belgrade fell to Mackensen on October 9; the Bulgarians crossed the Serbian frontier on the 11th, occupied Uskub on the 22nd, and Nish on November 5, thus opening direct railway communication between the Central Powers and Constantinople through Sofia. Monastir fell on December 2, and by the middle of that month the Serbian army and the Allies had been entirely driven out of Serbian territory.
