The local Norman population sought refuge in the castle to escape from the French soldiers who ravaged the town. The castle was well supplied for a siege, but the extra mouths to feed rapidly diminished the stores. Between 1,400 and 2,200 non-combatants were allowed inside, increasing the number of people in the castle at least fivefold. In an effort to alleviate the pressure on the castle's supplies, Roger de Lacy, the castellan, evicted 500 civilians; this first group was allowed to pass through the French lines unhindered, and a second group of similar size did the same a few days later. Philip was not present, and when he learned of the safe passage of the civilians, he forbade further people being allowed through the siege-lines. The idea was to keep as many people as possible within Château Gaillard to drain its resources. Roger de Lacy evicted the remaining civilians from the castle, at least 400 people, and possibly as many as 1,200. The group was not allowed through, and the French opened fire on the civilians, who turned back to the castle for safety, but found the gates locked. They sought refuge at the base of the castle walls for three months; over the winter, more than half their number died from exposure and starvation. Philip arrived at Château Gaillard in February 1204, and ordered that the survivors should be fed and released. Such treatment of civilians in sieges was not uncommon, and such scenes were repeated much later at the sieges of Calais in 1346 and Rouen in 1418–1419, both in the Hundred Years' War.
