At last she received intelligence that an armed force was ordered to assemble one night in the vicinity of Oatlands to seize her children, under the pretext that the queen was herself forming plans for removing them out of the country and taking them to France. Henrietta was a lady of great spirit and energy, and this threatened danger to her children aroused all her powers. She sent immediately to all the friends about her on whom she could rely, and asked them to come, armed and equipped, and with as many followers as they could muster, to the park at Oatlands that night. There were also then in and near London a number of officers of the army, absent from their posts on furlough. She sent similar orders to these. All obeyed the summons with eager alacrity. The queen mustered and armed her own household, too, down to the lowest servants of the kitchen. By these means quite a little army was collected in the park at Oatlands, the separate parties coming in, one after another, in the evening and night. This guard patrolled the grounds till morning, the queen herself animating them by her presence and energy. The children, whom the excited mother was thus guarding, like a lioness defending her young, were all the time within the mansion, awaiting in infantile terror some dreadful calamity, they scarcely knew what, which all this excitement seemed to portend. The names and ages of the queen's children at this time were as follows: Charles, prince of Wales, the subject of this story, eleven. Mary, ten. Young as she was, she was already married, having been espoused a short time before to William, prince of Orange, who was one year older than herself. James, duke of York, seven. He became afterward King James II. Elizabeth, six. Henry, an infant only a few months old. The night passed away without any attack, though a considerable force assembled in the vicinity, which was, however, soon after disbanded. The queen's fears were, nevertheless, not allayed. She began to make arrangements for escaping from the kingdom in ease it should become necessary to do so. She sent a certain faithful friend and servant to Portsmouth with orders to get some vessels ready, so that she could fly there with her children and embark at a moment's notice, if these dangers and alarms should continue.
