According to descriptions of the operations of hospital from the second half of the 12th century, the men's hospital was divided into eleven wards and could tend to more than 1,000 patients. The hospital admitted all sick, regardless of nationality or religion. The Hospitallers at this time also operated a field hospital that would accompany the crusader armies on expeditions, which was able to evacuate 750 seriously wounded men from the Battle of Montgisard (1177) for treatment in Jerusalem. The Hospitallers referred to their patients as "our lords, the sick" in a tradition that presumably originated with Gerard.
