The camp had to be built slowly. Even though Gawain drew up many regulations and plans, and even a draft for the next step in expanding and completing the camp into a permanent encampment, all of these ideas could not be realized overnight - considering the knowledge of most people at this period, there was zero literacy among the commoners and serfs, the knights had only basic reading and writing skills and home-trained warriors could only write out their own names and count to a hundred. Hence, things could only be put in place at a very slow rate.
Furthermore, there was a lack of manpower and the Cecil territory could not sustain many men at the moment.
After he understood the current situation in depth, Gawain returned to his tent and sat before his desk.
