They were even ignorant that they were conquered.

They had been forced to abandon the field, and the patriots had entrenched themselves upon the dyke, but neither Fort Saint George nor the Palisade had been carried, although the latter was in imminent danger.
Old Count Peter Ernest Mansfeld--a grizzled veteran, who had passed his childhood, youth, manhood, and old age, under fire--commanded at the land-end of the dyke, in the fortress of Stabroek, in which neighbourhood his whole division was stationed.

Seeing how the day was going, he called a council of war.

The patriots had gained a large section of the dyke.

So much was certain.
