Antwerp, Nov 20.

The conduct of the commandment of the citadel and of the garrison itself appears inexplicable: the French worked during the night, yet not a shot was fired at them, and at mid-day they had completed without injury what they had expected to have cost 2,000 men, if an active resistance had been given. At ten o'clock last the Belgian posts were relieved all round the citadel, as well in the town as in the country. At midnight several volleys of musketry were fired off from the citadel, in order to clear the atmosphere and to allow the garrison to see if the enemy was near. The French, though under arms, ready to begin their work, preserved a strict silence. The garrison went "to sleep," until the summons awoke them from their slumbers, they saw the French soldiers at work within hail: the soldiers and officers continued to look impassively until mid-day.

Antwerp, Dec. 1, one o'clock.

I have seen a military gentleman who has just returned from the trenches, and his report is as follows:--The French pushed forward zig-zag approaches from the parallel formed yesterday, of which the heads are now under musketry fire; and, to their astonishment, none has been opened as yet upon the workman.

This parallel was formed within 450 yards of the citadel; the approaches are consequently much nearer, and during this night their last parallel will, it is expected, be completed.

The platforms were at mid-day laid or laying for nine batteries, which, with the Montebello fort, will form ten, for 70 pieces of artillery, that are expected to open to-morrow morning. These batteries of eight heavy guns are to fire on the angle of the lunette.

EIGHT o'CLOCK.

General Sebastiani has summoned Forts Burcht and St. Hilaire to surrender. Colonel Carodoc in a British uniform, accompanied by a dragoon, is to be seen actively engaged at all parts of the city.

I have just heard that Chasse declares that he will respect the city-if the French do not attack the Tete de Flandre.

It is reported that an Englishman, and a Colonel of the French staff, have been killed.

TEN O'CLOCK.

It is reported to day that Chasse gave the following answer to the summons of Marshall Gerard:-

"Tell the Marshall that I intend to bury myself in the ruins of the citadel. As to the neutrality of the town, I make no promises; it will depend on circumstances and events."

HALF-PAST ELEVEN.

Chasse continues firing. There are very few either killed or wounded. It is reported that General Sebastiani took Fort St. Marie yesterday evening. It is said that he is now firing on the Comet frigate.
