General Gurko had been resting about the Shipka Pass with 5,000 men, including five battalions of Bulgarians. Some 15 battalions under Reouf Pasha joined Süleyman until his army reached about 30,000 Ottomans determined to retake the pass instead of simply bypassing it.

In September 1877, Suleiman Pasha made another attempt to retake the Shipka Pass from the Russians after the failed attempt in August. The Russian defenses had continually been improved since August but reinforcements were limited due to the siege of Pleven. On September 13, Suleiman began to shell the Russians. The bombardment continued in earnest until the 17th when Suleiman launched a frontal assault against the St. Nicholas position. Capturing the first line of trenches, the Ottoman forces moved towards the peak. General Fyodor Radetzky, now commanding the defenses, brought in reinforcements and a Russian counterattack drove the Ottoman forces from all captured ground. Secondary Ottoman assaults to the north were repulsed as well.

The Fourth Battle of Shipka Pass took place January 5–9 1878. It was the final battle for Shipka Pass and a crushing Ottoman defeat.

In December 1877, the fortress of Pleven surrendered to the Russian Army, freeing a significant number of Russian troops. General Gourko now had as many as 65,000 soldiers to contend with the Ottomans. Gourko forced the Araba Konak Pass and took Sofia. From Sofia, he moved south through the Balkan Mountains to cut off Ottoman access to Shipka Pass.

General Fyodor Radetzky, commanding the garrison, made preparations to attack from the pass on January 5 while Gourko brought up two columns under Generals Mikhail Skobelev and Nikolai Mirskii to cut off the Ottoman retreat. On January 8, Radezky's attack began but Skobelev was held up by unexpectedly heavy resistance and Mirskii attacked unsupported, making little progress. On January 9, Mirskii faced an Ottoman counter attack, but Skobelev was able to move forward in support and defeat the Ottoman forces. Completely surrounded, the remaining Ottoman forces under Veissel Pasha surrendered the same day.

The defensive victory at the Shipka Pass had strategic importance for the progress of the war. Had the Ottomans been able to take the pass, they would have been in a position to threaten the supply lines of the Russian and Romanian forces in Northern Bulgaria, and organize an operation to relieve the major fortress at Pleven which was under siege at that time. The war would have then been fought effectively only in northern Bulgaria from that point on, which would have led to a stalemate, which would have created a major advantage for the Ottoman Empire in peace negotiations. The Bulgarian volunteers played a decisive role in defending the Shipka Pass, thus denying the Ottomans a major breakthrough and a chance to turn the tide of the war. This strategic defensive victory illustrated their important role in the war and was dramatized by the Bulgarian poet and writer Ivan Vazov in his ode The Volunteers at Shipka. The victory at Shipka Pass ensured the fall of the Pleven fortress on December 10 1877, and set the stage for the invasion of Thrace. It allowed Russian forces under Gourko to crush Suleiman Pasha's army at the Battle of Philippopolis several days later and threaten Constantinople. With this victory and the conquest of Pleven at the end of 1877, the path towards Sofia was opened, and with it the path to victory in the war and a chance for Russia to gain an upper hand in the "Great Game" by establishing a sphere of influence in the Eastern Balkans. Suleiman Pasha was later court martialed due to the colossal failure at Shipka, even though the pass was already lost when he had arrived. His failure to seek alternatives, wasting of men and material that would have been essential later in the campaign, and his failure to secure his remaining troops were too blatant to forgive. He was initially sentenced to death but then commuted by Sultan Abdulhamid II and sent to exile in Baghdad. Today the Shipka Pass is in the Bulgarka Nature Park and is home to a monument commemorating the warriors who died in the battle.
