The Battle of Ras al-Ayn took place over 5 months and three phases during the Syrian Civil War. The Kurds (YPJ/YPG), vs the Syrian Arab Republic, vs Hasaka. I tried to summarize this Sittang, but Wikipedia does it better.

The third phase of the battle erupted when al-Nusra militants surrounded a unit of female YPJ fighters near Ras al-Ayn on 16 July, and arrested the group’s driver. The YPG/YPJ consequently mobilized their forces, deployed reinforcements to the town, and started a number of raids on key al-Nusra positions.^[28] Seeing a chance to take revenge on the insurgents, about 200 fighters of the Abu Jabal Brigade (an Arab government loyalist unit) joined the Kurds in their attack.^[10] After a night of fighting,^[6] the YPJ driver was freed, and the YPG had captured the al-Nusra Front’s local headquarters.^[28] By 17 July, the jihadists had mostly been expelled from the town,^[6] and the YPG/YPJ soon after took control of the border crossing with Turkey.^[8] Eleven people were killed during this phase of the fighting, including nine jihadist and two Kurdish fighters.^[66] The YPG/YPJ consequently advanced into the countryside to establish a defensive ring around Ras al Ayn, encountering heavy resistance. By 20 July, the Kurdish-led forces had secured the town and its surroundings.^[67]
