Later on in the evening, however, two of the messengers arrived with the news that the forts had surrendered. Prince Maurice then, in opposition to Vere's advice, sent off 2500 infantry, 500 horse, and 2 guns, under the command of Ernest of Nassau, to prevent the enemy from crossing the low ground between Ostend and the sand-hills, Vere insisting that the whole army ought to move. It fell out exactly as he predicted; the detachment met the whole Spanish army, and broke and fled at the first fire, and thus 2500 men were lost in addition to the 2000 who had been left to garrison the forts.
At break of day the army marched down to the creek, and as soon as the water had ebbed sufficiently waded across and took up their position among the sand-hills on the sea-shore. The enemy's army was already in sight, marching along on the narrow strip of land between the foot of the dunes and the sea. A few hundred yards towards Ostend the sand-hills narrowed, and here Sir Francis Vere took up his position with his division. He placed a thousand picked men, consisting of 250 English, 250 of Prince Maurice's guard, and 500 musketeers, partly upon two sand-hills called the East and West Hill, and partly in the bottom between them, where they were covered by a low ridge connecting the two hills.
The five hundred musketeers were placed so that their fire swept the ground on the south, by which alone the enemy's cavalry could pass on that side. On the other ridge, facing the sea, were seven hundred English pikemen and musketeers; two hundred and fifty English and fifty of the guard held the position of East Hill, which was most exposed to the attack. The rest of the division, which consisted of six hundred and fifty English and two thousand Dutch, were placed in readiness to reinforce the advanced party. Half the cavalry, under Count Louis, were on the right of the dunes, and the other half, under Marcellus Bacx, on the left by the sea.
The divisions of Count Solms and Count Ernest of Nassau were also on the sea-shore in the rear of West Hill. A council of war was held to decide whether the army should advance to the attack or await it. Vere advised the latter course, and his advice was adopted.
The archduke's army consisted of ten thousand infantry, sixteen hundred horse, and six guns. Marshal Zapena was in command, while the cavalry were led by the Admiral of Arragon. They rested for two hours before advancing—waiting until the rise of the tide should render the sands unserviceable for cavalry, their main reliance being upon their infantry. Their cavalry led the advance, but the two guns Vere had placed on West Hill plied them so hotly with shot that they fell back in confusion.
It was now high tide, and there were but thirty yards between the sea and the sand-hills. The Spaniards therefore marched their infantry into the dunes, while the cavalry prepared to advance between the sand-hills and the cultivated fields inland. The second and third divisions of Maurice's army also moved away from the shore inland. They now numbered but three thousand men, as the four thousand five hundred who had been lost belonged entirely to these divisions, Sir Francis Vere's division having been left intact. It was upon the first division that the whole brunt of the battle fell, they receiving some assistance from the thousand men remaining under Count Solms that were posted next to them; while the rear division was never engaged at all.
At half-past two o'clock on the afternoon of the 2d of June, 1600, the battle began. Vere's plan was to hold his advanced position as long as possible, bring the reserves up as required until he had worn out the Spaniards, then to send for the other two divisions and to fall upon them. The company of Lionel Vickars formed part of the three hundred men stationed on the East Hill, where Vere also had taken up his position. After an exchange of fire for some time five hundred picked Spanish infantry rushed across the hollow between the two armies, and charged the hill. For half-an-hour a desperate struggle took place; the Spaniards were then obliged to fall back behind some low ridges at its foot.
In the meantime the enemy's cavalry had advanced along the grass-grown tract, a hundred and fifty yards wide, between the foot of the dunes and the cultivated country inland. They were received, however, by so hot a fire by the five hundred musketeers posted by Vere in the sand-hills on their flank, and by the two cannon on West Hill, that they fell back upon their infantry just as the Dutch horse, under Count Louis, advanced to charge them.
Vere sent orders to a hundred Englishmen to move round from the ridge and to attack the Spaniards who had fallen back from the attack of East Hill, on their flank, while sixty men charged down the hill and engaged them in front. The Spaniards broke and fled back to their main body. Then, being largely reinforced, they advanced and seized a sandy knoll near West Hill. Here they were attacked by the English, and after a long and obstinate fight forced to retire. The whole of the Spanish force now advanced, and tried to drive the English back from their position on the low ridge across the bottom connecting the two hills. The seven hundred men were drawn from the north ridge, and as the fight grew hotter the whole of the sixteen hundred English were brought up.
Vere sent for reinforcements, but none came up, and for hours the sixteen hundred Englishmen alone checked the advance of the whole of the Spanish army. Sir Francis Vere was fighting like a private soldier in the midst of his troops. He received two balls in the leg, but still kept his seat and encouraged his men. At last the little band, receiving no aid or reinforcements from the Dutch, were forced to fall back. As they did so, Vere's horse fell dead under him and partly upon him, and it was with great difficulty that those around him extricated him. On reaching the battery on the sands Vere found the thousand Dutch of his division, who asserted that they had received no orders to advance. There were also three hundred foot under Sir Horace Vere and some cavalry under Captain Ball. These and Horace's infantry at once charged the Spaniards, who were pouring out from the sand-hills near to the beach, and drove them back.
