The Siege Of Ostend.
On the 5th of July, 1601, the Archduke Albert began the siege of Ostend with 20,000 men and 50 siege-guns. Ostend had been completely rebuilt and fortified eighteen years previously, and was defended by ramparts, counterscarps, and two broad ditches. The sand-hills between it and the sea were cut through, and the water filled the ditches and surrounded the town. To the south the country was intersected by a network of canals. The river Yper-Leet came in at the back of the town, and after mingling with the salt water in the ditches found its way to the sea through the channels known as the Old Haven and the Geule, the first on the west, the second on the east of the town.

On either side of these channels the land rose slightly, enabling the besiegers to plant their batteries in very advantageous positions. The garrison at first consisted of but 2000 men under Governor Vander Nood. The States-general considered the defence of Ostend to be of extreme importance to the cause, and appointed Sir Francis Vere general of the army in and about Ostend, and sent with him 600 Dutch troops and eight companies of English under the command of his brother, Sir Horace. This raised the garrison to the strength of 3600 men. Sir Francis landed with these reinforcements on the sands opposite the old town, which stood near the sea-shore between the Old Haven and the Geule, and was separated from the new town by a broad channel. He was forced to land here, as the Spanish guns on the sand-hills commanded the entrances of the two channels.
