So Frederick consented to become King of Bohemia, and he, Elizabeth, and their three little children left their beautiful Heidelberg home to be crowned king and queen. Great were the rejoicings; bells rang, bonfires were lit, cheers of "Long live King Frederick!" echoed through the air, while those who were near enough kissed the hem of the new queen's robes, for Elizabeth had already won their hearts; she ordered bread and wine to be given to all who came to the castle, and by her goodness and generosity won the name of "Queen of Hearts." But their position of King and Queen of Bohemia was not secure; jealousy began to show itself in the princes round them, and Frederick felt that at any moment the threatened storm might burst. He had been growing more and more unpopular, and at last war was declared. The more critical Frederick's position, the firmer grew Elizabeth. "I persuaded you to be crowned king, I was with you in those happy and joyous days, I will stand by you in trouble," she said, and not only said, but did. She sent away her children, only keeping Prince Rupert, a baby of but a year old. The first battle was lost, and in anguish Frederick hastened to his wife, begging her to escape at once. But she would not leave him. If he would come, she would go; if not, they would stay together. His subjects begged their king to stand firm; they reminded him of his oath to guard his kingdom to the last; a raid on the enemy might yet turn the scale. But where his wife's life was in danger, Frederick refused to stay, and together they escaped from their kingdom. Still relying on help from England, they hoped on, and Frederick again joined the army. Leaving behind her a baby of a month old and her other children, Elizabeth again followed her husband, knowing that she alone could cheer him and keep up his spirits. Once more she travelled through parts of the country where, only six years ago, she had been welcomed as a happy bride; now she wandered an outcast and an exile, with but the empty title of queen to make up for the loss of a home, country, friends. When Heidelberg, their lovely home, fell into the hands of the enemy, Elizabeth cried piteously, "My poor Heidelberg taken! Oh! God visits us very severely; the misery of these poor people distresses me sadly!" Still the war, known as the Thirty Years' War, went on, and Frederick was often away for many months together. In 1629, a terrible grief befell Elizabeth in the death of her eldest son Henry. He was in a yacht with his father one day, when a large vessel bore down upon them, and struck them; the yacht filled with water, and in a moment sank. All on board perished save King Frederick.
