about Bilbis, true I check that in google, the city between two small rivers though in the map it's looks very far from the main river. and about the wall see ibn Al-Esir [Al-Kamel] see year 559 [...the fattimeds and the frakish armies sieged the city and Shirkuh stand in front of them attacking and defending for three months yet it's walls very short and there no moats around it. ...] and you can find that in all muslims historian books from that time.
Shirkuh [short Biography by Imam Ath' Thahabi - Seyar Al-A'Alam, book 20 - number 269]
-Shirkuh first camping on egypt - year 559 Hijry
Shawar came Damascus in the last year asking Nur Ad'Din help against Amir Al-Juyoosh Thegham the the current Fattimed Wazir and promise him he will give him 1/3 of egypt treasury annually. first Nur Ad'Din was doubtful becuase the Franks were between them and Egypt and he fear if Shawar get back to his position he will betray them, but after some time he decided to help Shawar and he didn't find a man in his Kingdom more fit to this metion more than Asad Ad'Din Shirkuh. Nur Ad'Din call Shirkuh from Aleppo and when he arrive he ordered him to march to Egypt with Shawar but Shirkuh first refused the order saying to Nur Ad'Din "I'll not march with 1000 Faris to country that have 10000 Faris and 100 shini [I didn't find what is Shini] with 15000 warriors and they have 40000 slavewarriors for 5 Caliphs" [see I'taath Al-Hunafa (اتعاظ الحنفا بأخبار الفاطميين الخلفا) - year 559]. Nur Ad'Din however knew that will be Shirkuh reaction and he call a sheihk Naja who toled Nur Ad'Din that while he was in a visite to Egypt he been toled by one of the Sufi Sheihks in Egypt that Shirkuh will take Egypt and Nur Ad'Din toled not to toled any body. nw Nur Ad'Din call him and first thing he asked him :"did you toled any body" , and after Nur Ad'Din check that he didn't toled anybody he send to tell Shirkuh. and that how Shirkuh first accept to go Egypt.
Nur Ad'Din order Shirkuh to march to Egypt with Shaear and he himself march near Karack and Shoubak to keep the Franks attention on him. Shirkuh go through the desert and march south in Sina Desert. nobody notice Shirkuh until he was near Bilbis [Bilbais]. while Thergham was training to delay the payment to the Franks he reserved a Letter from his Brother Amir Husam Ad'Din the Mutawali of Bilbis informed him by the arrival of Shirkuh and Shawar and the Turks with them. the next day all people in cairo had heard the news and they starting to move from thier houses and gather food and water as they used to do [*in wars between viziers].
after about tow weeks in Saturday Thergham sends his brother Naser Al-Muslmeen Humam with about 6000 Faris with the covered horses and the valuable armor and the wonderful arms and they were proud of them self and comfort of wining the small battle. they reach near Bilbis in Sunday and Shirkuh shows in Monday and they both rested Monday's night. in the morning Shirkuh was shocked and look to Shawar and say "You, you said their no armies in Egypt, until you brought us with this small numbers" ,but Shawar replay and said "Don't be afraid of thoses, most of them are workers and farmers. What you think the able to do in the battle. those are gathered by drummed and separated by sticks. and about the Amirs their letters are with me and they promise to aid me, but I want you to order the troops to be prepared" . the Fattimeds troops waited the Turks to attack until their armor become hot in the middle of the day. they dismount and built their tents and some of them even through their arms and armor. that what Shawar was Waiting. he tell Shirkuh now is the right time to attack. Naser Ad'Din Humam and Amir Faris Al-Muslmeen charge on the turks troops but Humam injured and when he look behind him, but there was nobody else even Al-Maqrizi says "and the Bravest of them was who mount his horse". They run to Bilbis and Shirkuh go after them and take the city after it’s governor run too. His troops become better after they take the fattimeds arms and armor. the few fattimeds troops been captured were mostly of Amirs, they join hem after he free the Amirs. Amir Humam reach AL-Qahira next day and his brother the Mutawaly of Bilbis Amir Hasan been captured after some of Kinanah tribe guide shirkuh to him.
After two days Shirkuh was in place called At'Taj in front of Al-Qahira [*Cairo]. and his soldiers spread around to find food for them and for their animals. Thergham already call the governors and their troops including the Rayhaniyyah [*Shawars troops] and Jayshiyyah and who left of the Burqiyyah and gather them all in Al-Qahira [*Cairo. Cairo in the Fattimeds time were made off two parts, the old city (generally historian of that period called it Misr) were the people live and their daily life and Al-Qahira which built by Al-Mu'Ezz and in it the Palace, the Azhar Mousqe, Dawaeen (offices of the vizier and others) and the soldiers houses. People were not allow to enter Al-Qahira without official order. Even all visitors and ambassadors who enter Al-Qahira should dismounted and go to the palace between tow lines of guards]. Then Shawar take oath from Shirkuh that they don’t betray him nether deliver him to Thergham or abandon him unless they been defeated. And some of Kinanah tribesmen were attacking Thergham troops here and there because he kills some of their Amirs. Shawar then moved from Kharaqaniyyah to Al-Maqus toward Al-Qahira so Thergham’s Armies march to him and attack him near Al-Maqus. The Amirs who were freed before near Bilbis join Thergham’s side what caused bad defeat to Shawar and Shirkuh. Thergham after his victory near Al-Maqus sends to the Qathy Al-Quthat [High Judge] to bring the orphans money from the treasury what. Shawar and Shirkuh moved to habash [in the south] then they take the old city where the people’s lives because they dislike Thergham after he take the orphans money and he was threaten them if got Shawar that he will burn their houses. And that strengthen Shawar and Shirkuh. Shawar and Shirkuh left the old cit and March toward Al-Luq [to the west of AL-Qahira, to find more about Cairo and its doors, location and its range see “Al-Mawa’Eth wa Al-E’Etebar fi Thekr Al-Khutab wa Al-Aathar” ( المواعظ و الإعتبار في ذكر الخطب و الآثار – تقي الدين ابو العباس أخمد بن علي الحسيني العبيدي المقريزي ) – Abu Al-Abbass al-Maqrizi ] and defeated Thergham’s Cavalry and the fight moved Qantarah and Sa’Aada doos and by the night and The Rayhaniyyah troops join Shawar. And when the Caliph saw Thergham was losing he sends orders to the archer not attack anymore and by the morning Thrghams was outside Al-Qahira running from door to door in 500 Fursan only and he order to call the soldiers to fight but no one get out to him so return inside d stand near Rahbah door near the the Caliph palace. Shawer sends his son Sulayman to control the Qantarah door. After that the fight stop and Thergham try to call the Caliph to show up from his window but there was no answer. Thergham stand their trying until the afternoon and left 30 Fursan and he reseved a letter in it “save yourself and get out of here”. Shawar enters Qahira from Qantarah door after he request that from the Caliph. Thergham knew that shawer interning by the sounds of the Turkish horns that first time they been heard in Cairo and after that Shawar’s Ghulams attacked Thergham and one of them managed to stab him with dagger.
