حصار وادي الضيف
حصار وادي الضيف أو معركة البنيان المرصوص، هو حصار قام به الجيش السوري الحر على قاعدتين عسكريين سوريتين، وادي الضيف، والحمادية، بدأ في 11 أكتوبر 2012، وانتهى في 18 أبريل 2013، أثناء الثورة السورية. تكمن أهمية المعركة، في أن قطع الجيش لطريق الإمدادات عن مجموعات الثوار، أصابها بالشلل الكامل، حيث يعتبر هذا هو الطريق الوحيد لها، لنقل الذخيرة والعتاد والأفراد. 
تكمن أهمية القاعدتين العسكرتين وادي الضيف والحامدية، أنهما يقعان غرب مدينة معرة النعمان وعلى بعد 500 متر من طريق حلب ـ دمشق الدولي. وإن عمل جبهة النصرة والمجموعات المسلحة للسيطرة عليهما، كان ينحصر في عدة أسباب أهمها، قطع طريق الامداد ونقاط العبور نحو الحدود الشمالية مع تركيا. وهذا سيؤدي الى قطع طريق الامداد أمام الجيش السوري لمد قواته التي تخوض معارك حلب وريف إدلب بالدعم، ما سيعزز سيطرة المسلحين على مناطق شمال غرب سوريا، بعد أن دخل الثوار لمدينة معرة النعمان.
قام الجيش السوري بعمليته العسكرية، حيث بدأ بالتقدم في معرة النعمان، ليشرع بتأمين الطريق الدولي بين خان شيخون ومعرة النعمان، وصولاً لموقعي وادي الضيف والحامدية، من محوري بلدتي بابولين والتح. وقطع طرق الامداد عن المجموعات المسلحة التي تحاصر موقعي وادي الضيف والحامدية، كما قام بإحداث نقاط تمركز عسكرية له على الطريق.
في 8 أكتوبر، قام الثوار بهجوم للاستيلاء على بلادة معرة النعمان، والتي تتمتع بموقع إستراتيجي خلف الطريق السريع الخامس، طريق رئيسي للتعزيزات العسكرية المرسلة من دمشق والتي كان الجيش السوري يستخدمها أثناء معركة حلب. في 10 أكتوبر، كان الثوار قد استولوا على المدينة وبعد ثلاثة أيام قاموا بصد التعزيزات السعكرية التي كانت قد أرسلت في محاولة من الجيش الحكومي لإستعادة البلدة. ومع ذلك، فقد ظلت القاعدتين العسكريتين في ضواحي معرة النعمان تحت سيطرة الجيش مما دفع الثوار لضرب حصار وهجمات متوالية للإستيلاء على القاعدتين.
الهجمات الأولى للثوار
في 11 أكتوبر، قال مراسل إي إف بي أن الثوار كانوا يسيطرون على خمسة كم من الطريق السريع الخارج من المدينة. في اليوم نفسه شن الجيش السوري الحر هجوماً على وادي الضيف المحاصر، والذي كان يستخدم كموقع للهجوم على معرة النعمان، شرق الطريق السريع. استخدم الثوار إحدى الدبابات المستولى عليها، وقنابل هاون وأر بي جي، واستمرت الغارات الجوية على البلدة.
في 14 أكتور، قامت القوات الحكومية بمحاولات لصد هجوم جديد من قبل الثوار على القاعدة العسكرية مع إحتدام القتال في قرى المعرشورين والهيش المجاورة. في اليوم التالي، قام الثوار بصد الجيش عن البلدة إلى ثكنتين عسكريين في ضواحيها. وصف قادة الثوار هذا التقدم على أنه "انفراجة كبيرة".
إرسال التعزيزات العسكرية
On 15 October, a column of reinforcements was sent to make an attempt to break through to the base.
On 16 October, the military counter-attack continued with additional air-strikes on the town and surrounding areas. The next day, a military attack helicopter was shot down during fighting in Maarhtat, on the outskirts of Maarrat al-Nu'man.
On 18 October, military fighter jets destroyed two residential buildings and a mosque, where many women and children, who had thought the danger had passed and returned to the town, were taking refuge. Rescue workers said the airstrikes had killed at least 44 people. 23 children were among those killed in the airstrike, including a nine month old baby, according to the workers. In the evening, the rebels launched what they said was a “final assault” on the Wadi Daif military base. The rebels claimed to have destroyed three tanks and captured six soldiers in the fighting. Hundreds of rebels were involved in the operation, according to an AFP correspondent. The rebels captured the fertiliser storage area, which is part of the military complex, and killed six soldiers, according to SOHR.
On 19 October, rebels announced they had removed part of a collection of mosaics from the city's museum in order to protect it from ongoing bombardment. The collection was reported to have suffered little looting, though a pre-Islamic era coin collection has gone missing. On 8 October a government jet dropped a bomb close to the building's entrance, shattering its doors and damaging some of the more fragile pieces.
By 20 October, rebels had encircled Wadi Deif on three sides. The base was defended with at least 15 tanks and 250-500 troops. Soldiers inside the base were relying on airdrops for resupply, however most were missing and falling into rebel areas or no man's land. Meanwhile, Army reinforcements had advanced to five kilometers south of Maarrat al-Nu'man, but were still being held back by rebel forces.
On 21 October, four tanks were destroyed as the reinforcement column tried to reach the base.
On 23 October, government air-strikes on Maarrat al-Nu'man and the village of Mar Shamsheh killed and wounded more than two dozen rebels. By this point, the battle for the Wadi Deif base had been going on for two weeks. The fall of the base would result in government forces having only one land route to resupply their forces in Aleppo, via the port of Lattakia. Government control of the base meant the rebels could not claim full control of Maarrat al-Nu'man. The military was using airdrops to resupply the soldiers at the base with bread and other food. Government forces had also been using continuous attacks along the M5 highway to link up with the besieged soldiers based in Wadi Daif. The base itself is believed to hold 5 million liters of kerosene according to a defected army officer. By taking the base, the FSA would also be able to protect their flank and then advance on Jisr al-Shughour and block supply and reinforcement convoys coming in from Latakia for Aleppo.
On 25 October, despite rebel attempts to stop their advance, the military armored column, sent to reinforce the base 10 days before, had arrived near Maarrat al-Nu'man. They deployed south of the town and started shelling rebel forces that were attacking Wadi Daif, thus curbing the two-week-old rebel siege of the military base.
On 26 October, at 10:30am (local time), rebels, including the Islamist Al-Nusra Front, attacked government positions near the Wadi Dief base sparking 'fierce clashes' between the two sides. The Army responded by shelling Deir Sharqi, a nearby village. It is considered to be the first violation of the attempted ceasefire for the Muslim holiday of Eid al-Adha, according to the Syrian Observatory for Human Right. The Al-Nusra Front had earlier warned that, although not the only group to do so, there was "no truce between us and this transgressing regime". According to SOHR, rebels shelled a building in the Waif Dief complex, completely destroying it and killing 9-10 soldiers. SOHR also reported four rebels were killed at the perimeter of the base during the fighting.
On 27 October, in spite of the truce, government forces were moving convoys full of reinforcements up the road to Wadi Deif. FSA fighters were struggling to stop their advance.

On 30 October, rebels clashed with Syrian Army troops south of the city, killing two soldiers and two members of Al-Nusra Front. Also, the military shelled the nearby village of Maarshmareen. Rebel fighters and Syrian Army forces fought new gun battles around the besieged Wadi Deif army base. 28 civilians were killed by government bombings of the city. Rebel fighters had largely left the town itself for the front lines outside of it.
On 31 October and 1 November, air-strikes on the city intensified as clashes just south of Maarrat al-Nu'man continued. The siege of Wadi Deif continued with FSA units, backed by the Al-Nusra Front, trying to capture the base.
By early November, rebels were beginning to fear that they might have to withdraw from the city. Insufficient coordination, supplies, and firepower combined with the intense army pressure and counter-attacks from air and ground make holding the city a "costly" for them. Rebels have also had to use their own monthly wages (US$150) to buy ammunition. Despite the continuous siege of Wadi Deif, the army has kept the base supplied on a regular basis.
By 10 November, after 10 days of fighting, Syrian forces gradually recaptured villages along the highway that leads to Maarrat al-Nu'man. These villages fell to the rebels in early October. Combined with the recent resupply of food and ammunition to the besieged Wadi Deif base, fighting intensified between the two sides. Although government forces had not yet entered the town of Maarrat al-Nu'man and the siege of the Wadi Deif continued, pressure increased on rebel forces in the area.
On 14 November, Syrian forces launched two air strikes on Maaret al-Numan while continuing their attempt to retake the town from the rebels, a battle which has been ongoing since 9 October.
On 19 November, rebels and loyalist soldiers clashed south of Maarrat al-Nu'man on the highway and nearby villages. Rebels still controlled the city and the highway entrance to the town. Rebels destroyed two tanks and shot down one helicopter. Rebel fighters also made another advance onto the Wadi Deif army base, where heavy fighting erupted.
On 22 November, rebels claimed to have destroyed two government tanks near the Hamidieh checkpoint.
By 26 November, the vast majority of the city's 150,000 original inhabitants had fled. Much of the city lay in ruins; government media labelled the destruction as the result of a magnitude 6.6 earthquake, but residents maintained that unrelenting shelling of the rebel-controlled city by the military was the actual cause. The stretch of highway running south of the city to Damascus was reportedly under government control, while the stretch running north to Aleppo was not under the firm control of either side. The parallel military highway remained open, but was characterised as a very slow and inefficient supply line due to the roughness of the road.
هجمات الثوار في ديسمبر ويناير
FSA fighters launched another attack on the base on 25 December, in what was described as the heaviest fighting in months in the area. The attack was commenced by a car bomb and than mortars. 20 rebels, including a "commander" were killed in the fighting.
By 29 December, the renewed rebel offensive against the Wadi Deif base was faltering due to a lack of supplies.
Following the failed December offensive, questions were being raised who was responsible for the rebel failure to capture Wadi Deif. The main cause was pointed to be the divisions among different rebel groups, a lack of coherence in their joint operations due to competition for loot, uneven funding and, according to one report, firebrand clerics who lack an understanding of battle field realities.
In January, more coordinated and planned rebel assaults were launched against the bases, however they too were repulsed with at least another 26 rebels being killed.
On 7 February, Time Magazine reported that a council of clerics, led by Jahbat al-Nusra, was marshaling supplies and organizing multiple rebel groups around Maarat al-Nu'man, including Suqour al-Sham and the FSA's Idlib Revolutionary Military Council, for a new offensive against the besieged Wadi Deif base. The large government base of Wadi Deif houses an armored regiment and the rebels believe it also holds millions of liters of fuel in underground silos.
On 10 February, intermittent clashes took place between regime forces and fighters from several rebel battalions around Wadi al-Dayf and the Hamidiya checkpoint. Areas in Ma'arat al-N'uman city and the Kafruma town were bombarded.
On 11 February, it was reported that armed fighters—allegedly from Jabhat al-Nusra—shot at and beheaded a statue of the blind poet and philosopher Al-Maʿarri, who was born in the city during the Abbasid era. Al-Maʿarri was known for his criticisms of religion, including Islam.
On 7 March, a Syrian fighter-jet was downed by anti-aircraft machine-guns while it was bombarding the town of Heish and its surrounding area, in southern Reef Idlib, south of Ma'arat al-Nu'man city. A SOHR activist witnessed the plane falling after it was hit, with black smoke coming out of it. Eyewitnesses reportedly saw the pilots parachuting out of the plane.
