Saladino não concluiu com sucesso os seus cercos em Kerak em 1183 ou 1184. Provavelmente esse fato reflete sua cautela, uma vez que Montgisard, em 1177, lhe ensinou que enfrentar o exército cristão em seu próprio terreno era muito perigoso.
Throughout history, we have seen military leaders who by displaying courage in the face of their disability won the respect and admiration of their men. King Baldwin IV was a leper, and yet was a successful monarch who defeated Saladin at the Battle of Montgisard.
Encouraged by their success at Montgisard, in the autumn of 1178 the Franks made a highly aggressive move. They started to build a castle at Jacob's Ford on the River Jordan. The construction of this fortress, about 55 kilometres from Damascus, signalled a genuine challenge to the Muslims and again showed Saladin the scale of the task he faced to defeat the Franks.
‘That Saladin did not successfully conclude his sieges at Kerak in 1183 or 1184 probably reflected his caution. Montgisart in 1177 had taught him that confronting the Christian army on its own ground was dangerous’ (p. 73).
