P: After the battle of Kirk Kilisse the Bulgarian high command decided to wait a few days, a decision which allowed the Ottoman forces to occupy a new defensive position on the Luleburgaz-Karaagac-Pnarhisar line. Despite this, the Bulgarian attack by the First and Third Army which together accounted for 107,386 rifleman, 3,115 cavalry, 116 machine guns and 360 artillery pieces defeated the reinforced Ottoman Army consisting of 126,000 riflemen, 3,500 cavalry, 96 machine guns and 342 artillery pieces and reached the Sea of Marmara. In terms of forces engaged it was the largest battle fought in Europe between the end of the Franco-Prussian War and the beginning of the First World War. As a result of it the Ottoman forces were pushed to their final defensive position across the Catalca Line protecting the peninsula on which Constantinople is located. There they succeeded in stabilizing the front with the help of fresh reinforcements from the Asian provinces. The line had been constructed during the Russo-Turkish War of 1877-8 under the directions of a German engineer in Ottoman service, von Bluhm Pasha, but was considered obsolete by 1912. An epidemic of cholera spread among the Bulgarian soldiers after the Battle of Luleburgas - Bunarhisar.

P: The Mongol invasions of 1236-1241 left the Russian principalities subjugated by the Golden Horde. In the 13th-15th centuries, the Khan of the Golden Horde appointed the Great Prince, who in the 14th century resided in Moscow. In the 13th century the medieval Rus' consisted of a set of relatively small and weak principalities, fighting and making alliances against each other. The larger states progressively conquered or absorbed the smaller ones. One bigger principality, the Grand Duchy of Moscow, grew due to a series of clever policies and became the biggest one in central Rus'. In 1380 Dmitry Donskoy, the prince of Moscow, even managed to fight the troops of Golden Horde in the Battle of Kulikovo and win. Whereas formally Moscow remained dependent on the Horde, and the Khan needed to approve position of the Prince, the Grand Duchy of Moscow had become a major regional power, and the Moscow princes aimed to conquer the remaining lands around Moscow and to append them to their Grand Duchy.
