As the canisters of chlorine gas fell inside Carrickfergus Castle, the defenders felt fear.
This was because they did not understand that it was that greenish mist that was in the environment, however they were sure of something and it was that the mist was covering the castle doors.
The defenders, when seeing this mist prepared themselves, however when the first screams began to be heard, the defenders realized that things were much more dangerous than they thought.
Because of the large number of people that were crowded on the walls, the defenders fought to escape.
Some preferred to jump to try to survive, however, because of the green mist it was completely impossible to see where they could fall, but despite that they took a risk.
So many of them jumped on the snow, saving their lives, but that was momentary because a few warriors fell on them, which crushed them, not to mention that the chlorine gas mist was dangerous in that place.
