Before Monday’s operation, the population was 6,000 to 8,000. By the end of the day, the government announced that it had relocated 2,318 people.

Judging by the crowds on Monday, many of the migrants appeared set to shed their dreams of Britain and were as anxious to be rid of the camp as the government was. On Tuesday, French officials plan to start demolishing and clearing its flimsy shacks, fields of tents and piles of trash spread over 1.5 square miles.

While the clearing of the camp was peaceful, the police warned that they were expecting some resistance from activist groups, if not from the migrants themselves, when the demolition begins on Tuesday.

“The Jungle is no good,” said Abdullah Umar, 24, who is from Sudan’s war-torn Darfur region and hoped to apply for asylum in France. He was waiting in line on the road. “There are problems. Sometimes there’s fighting. And it’s cold.”

Mr. Umar added: “France is a good country. People from France gave me all these clothes.” He pointed to his new suitcase, which looked packed full.

Hassan Jibril, 35, another Sudanese man, trying to keep himself warm in the Jungle’s warren of tents, said, “We are ready to leave.”

He was wearing flip-flops in the 40-degree chill and heating some pots over an outdoor fire. “It is a very bad situation here,” he said. “You see that?” he said, pointing to a trash-filled puddle next to his tent. “If you stay here, you can die.”
