ISIS began on September 15, 2014 with a massive attack on the villages of Kobani, which ISIS was besieging on three sides while Turkey was besieging the fourth.
Along three fronts and hundreds of kilometers, ISIS began massing its forces on the edge of Kobani canton. After taking control of Mosul, as well as many military sectors of the Syrian regime army, most notably the 93rd Brigade in Ain Issa, where it seized large tons of weapons and dozens of armor used in its attack on the canton.
The plan was apparently well-planned, which did not save time until the offensive began on two fronts together, from the east and the west, and quickly occupied a number of villages because of the great strength it had when compared to those held by the YPG.
Kobani's defense forces never had one tank or even armored personnel carriers, unlike the ISIS mercenaries used on each front more than two tanks, not to mention the use of 130 cannons that were able to bomb Kobani city center from 30 kilometers away Kilometers.
The mercenaries began to attack and penetrate deep into the natural boundaries of Kobani which was protected by the YPG.
In the face of ISIS's military and numerical superiority over the YPG and the women, the units showed great resistance in which dozens of martyrs were martyred, and many of them carried out guerrilla operations such as Rivana, Arin Mirkan, Baran Serhad, Irish and Zozan, trying to deter and prevent enemy forces from advancing.
But the resistance with individual weapons and a few machine guns was not enough to stop the advance of ISIS towards Kobani.
The resistance in the countryside had a somewhat different character than the one that followed in the streets of the city. The YPG's retreat was the first ever since the units were established, which prompted the YPG fighters to challenge the fact that it was impossible to retreat one step back.
As the attacks intensified, civilians only had to flee to the center of the city, where the siege was intensifying with the passage of days and very quickly, in order to avoid certain massacres that could be exposed to them similar to those that took place in Shengal and killed more than 5,000 Yazidi people.
In 10 days, Kobani saw the displacement of more than 300,000 civilians towards the northern border of the canton with Bakur(North Kurdistan).
Most civilians crossed the border with northern Kurdistan and went to Seroj area of Turkey.
On the morning of Sunday, October 5, 2014, ISIS occupied Mashta al-Noor hill overlooking the city from the south-east after 20 days of fighting in the countryside and began to bombard it violently.
The battles that began in the city of Kobani in the form of street warfare developed in three stages. The first phase was to establish a defensive line to curb the advance of ISIS mercenaries, which was achieved on 8 October, three days after the fighting moved into the streets of the city.
In that day a number of YPG carried out guerrilla operations in which they targeted all the positions where the mercenaries were shooting the city from and managed to limit the advance of the ISIS's mercenaries.
Most of the talk was about the fall of the city at any moment and everyone was promoting it according to his interests, everyone was wondering whether Kobani fell or not? And when it will fall?
In the battles of Freedom Square, the advance of ISIS was limited, and the YPG began to fortify its defense lines and trained fighters in street warfare techniques. Thus, the days went by as attacks on the defense lines continued on a daily basis without the mercenaries making any progress. In fact, the YPG liberated from time to time some houses and streets, and the situation lasted for 71 days.
Then the second phase began, with the YPG beginning with hit-and-run tactics, ambushing, laying mines, sniping and many other tactics. A number of unit commanders also confirmed at the time that the strikes inflicted by ISIS mercenaries were due to operations carried out by their forces outside the city.
The third phase began on 18 December 2014, the 94th day of resistance. On that day, the campaign to liberate the city of Kobani began under the name of the campaign of revenge for the martyrs of Kobani.
With start of the campaign which lasted 40 days till liberating the city, the war balance changed completely.
Regional and global interaction with Kobani
The great resistance showed by the People's and Women's Protection Units(YPG and YPJ) in defending the city of Kobani attracted the world's attention toward the city of Kobani Within a short period of time Kobani became the headlines of most of the media and the speech of the most prominent international leaders.
Upon the arrival of ISIS in Kobani, the Kurds in northern Kurdistan (Bakur) were the first to rise up in support of the resistance that the YPG had been demonstrating in Kobani.
Hundreds of Kurds went to the border at the city of Persus, which borders Kobani, including some who crossed the border to participate in the defense of the city.
The popular uprising of the people of northern Kurdistan took place on 6, 7 and 8 October, in which about 40 civilians were repressed by the Turkish authorities in an attempt to suppress the voices calling for the uprising in support of Kobani.
A month and a half after the resistance began in Kobani, on November 1, the International Day of Solidarity with Kobani was declared at the invitation of intellectuals and senior jurists in the world, where thousands came out in more than 90 cities belonging to 30 countries in the world to embrace the resistance of Kobani, under the slogan “Global Mobilization for Kobani and Humanity against ISIS."
The Liberation of Kobani
After the attack on Kobani on September 15, 2014, and after 20 days of the battles of the campaign, ISIS was able after 94 days of fighting to control 70 percent of the total area of Kobani.
This resistance paved the way for the intervention of the international coalition to fight ISIS led by the United States to support the YPG and YPJ in the battles to defend the city.
The troops in Kobani were able to defeat ISIS mercenaries and liberate strategic points from each battle.
The YPG and the women in the battles of Kobani embodied heroic epics of redemption when they managed to liberate the city of Kobani after 134 days of continuous fighting.,
On January 26, 2015, the liberation of the entire city of Kobani from mercenaries was announced where the troops removed the last black flag from its sky and replaced it with green, red and yellow flags.
The resistance of Kobani rather than the resistance of the Kurdish people was an international resistance in which the sons of nations and various components participated, the Arab fought alongside the Kurd, the Kurd fought alongside the Persian and the Persian fought alongside the American, British and German.
In Kobani, many international fighters were martyred and most of them were Turks, which proves well that Kobani's resistance was a global international resistance, and its victory meant a victory for all nations.
The end of ISIS started from here
Undoubtedly, the resistance of the YPG in Kobane, which resulted in a major and severe defeat of ISIS, was the first defeat of the mercenaries.
Before defeating ISIS in Kobani, the armies of the region could not stand in the way of the mercenaries' march if they headed towards a city or region. Mosul, the second largest Iraqi city, fell to ISIS within hours, as was the Syrian city of Raqqa, and dozens of other cities.
The war of "eliminating ISIS in the city of Kobani", so to speak, in which ISIS reportedly lost 6,000 of its mercenaries and many more wounded, led to the retreat of ISIS forces, which later could not resist the military campaigns by SDF and the People's Protection Units to liberate the Syrian areas from ISIS north and east of the country.
As a result, the US-led International Coalition to Combat "Daesh" with the YPG and YPJ formed an alliance and established SDF which in turn liberated east and north of Syria.
There is no doubt that the defeat of ISIS in Kobani has greatly affected the retreat of mercenaries in Iraq as well.
Before the ISIS attack on Kobani, the mercenaries were constantly expanding, while the situation changed after the defeat of ISIS in Kobani. The mercenaries began to lose the territory they had controlled until they were completely defeated in the village of al-Baguoz in Deir ez-Zor countryside in March of this year after more than 4 years of war against this terrorist organization.
