Background
Mackensen took unified command of Central Powers forces in Dobruja after recognizing the strategic opportunity. The loss of Constanța was catastrophic — it had been Romania's primary port for receiving Allied supplies, and its fall drew Allied criticism of Romania's military performance.
Campaign: Dobruja Campaign 1916
Forces Engaged

The Battle

Second Allied attempt to break the Cobadin line failed. Mackensen assumed overall command and launched a counter-offensive that drove allied forces north of the Cernavoda–Constanța railway. Constanța fell October 22, depriving Romania of its Black Sea supply line.
The Second Battle of the Marne (in ) or the Battle of Reims (15 July – 6 August 1918) was the last major German offensive on the Western Front during World War I. The attack failed when an Allied counterattack by French and American forces, including hundreds of tanks, overwhelmed the Germans on the right flank, causing them heavy losses. Germany's defeat marked the beginning of the Allied Offensive, which culminated in the Armistice of Compiègne signed approximately 100 days later.
“"The counter-attack came like a hammer blow. We had barely reformed when Mackensen struck our left flank — by evening the railway was cut and there was no going back to Constanța." — Romanian officer's account, October 1916
Casualties & Outcome
~8,000 total killed, wounded, captured (Romania / Russia); ~5,000 total (Bulgaria / Germany / Ottoman)
Bulgaria / Germany / Ottoman achieved victory over Romania / Russia.
Romania lost all of southern and central Dobruja. The Allied forces retreated to a bridgehead north of Cernavoda. Constanța port was lost Oct 22, ending seaborne supply. Mackensen's forces now threatened Romania's rear while Falkenhayn pressed from Transylvania.
