Their fire was concentrated on Forts Waelhem and Wavre, south and east of Antwerp. Both had been destroyed by 1 October, and the reservoir near the former, which supplied the city with water, was broken down, flooding the Belgian trenches north of the Nethe, beyond which they had now taken refuge. Farther to the left Termonde was seized by German infantry and the Belgians driven across the Scheldt. On the 2nd the Government resolved to leave Antwerp, but its departure and the flight of the civilians were postponed by the arrival of Mr. Churchill, First Lord of the Admiralty, and first a brigade of Royal Marines and then two naval brigades of splendid but raw and ill-armed recruits. They were at once sent out to help the Belgians to defend their trenches along the north bank of the Nethe against the German numbers and their more effective shells. On the 5th and following night both the left and centre of the defence were pierced, the Germans crossed the Nethe, and began to concentrate their howitzers on the inner line of ramparts. On the 7th the exodus from the city began by land and water, and amid heartrending scenes a quarter of a million people strove to reach the Dutch frontier or safety on the sea. The Belgian and British troops did their best to hold off the Germans while the flight proceeded and the city was subject to bombardment. It was doubtful whether any would get away, for the Germans had at last begun serious fighting up the Scheldt in order to cut off the retreat towards Zeebrugge and Ostend. In the narrow gap between the intruding Germans and the Dutch frontier some were forced across the latter and interned; others fell into the enemy's hands; and less than a third of the first Naval Brigade escaped to England. On the 9th the bombardment ceased, and on the 10th the Germans made their formal entry into a well-nigh deserted city. They had got their pistol pointed at the heart of England, but like Napoleon they learnt that it was a pistol which could only be fired by sea-power.
