After the battle of Blenheim, August 2nd, 1704, in which she was in the midst of the fight, under the hottest of the fire, Christian was appointed one of the guard despatched with the prisoners to Breda. Having halted to refresh themselves with a pint of beer and a pennyworth of bread each (the prisoners being allowed the same indulgence), Christian saw the long-lost Richard Welsh, now a sergeant in the Earl of Orkney's regiment of foot, making love to a Dutch woman. She abused him heartily at first, but she soon forgave him. It was agreed that she should remain in the army and pass as his brother. On her return to her regiment she assisted in the siege of Landau. Nothing of any consequence happened to her during the campaign of 1705. On the 23rd of May, 1706, was fought the great battle of Ramilies. When the French were retreating, Christian, who had fought valiantly during the engagement, was struck in the head by "an unlucky shell" fired from a mortar planted on the steeple of the church. Her skull was fractured, and she was carried to the hospital of Meldré or Meldret, where her head was trepanned. During a ten weeks' illness the long-dreaded discovery of her sex was made. The surgeons sent word to Brigadier Preston that his "pretty Dragoon" was a woman. The Brigadier, who would at first scarcely believe the news, told Christian that he had always looked upon her "as the prettiest fellow, and the best man he had." The story soon spread through the regiment, and Christian was visited by Lord John Hayes and all her officers and comrades. Lord John gave strict orders that she should want for nothing, and promised that her pay as a dragoon should be continued till she had quitted the hospital. Of course she could no longer stop in the regiment. "Brigadier Preston" she says "made me a present of a handsome silk gown; every one of the officers contributed to furnishing me with whatever was requisite for the dress of my sex, and dismissed me the service with a handsome compliment." Her husband having been questioned relative to their previous acquaintance, it was thought prudent to have them married again; and this second wedding was celebrated with much solemnity, in presence of all the officers, "who, everyone, at taking leave, would kiss the bride, and left me," adds Christian, "a piece of gold, some four or five, to put me in a way of life." For a short time she carried on the business of cook to the 6th Dragoons; but finding the work too heavy, she turned sutler, and was permitted, as a special favour, to pitch her tent in the front of the army, the other sutlers being driven to the rear. She spent much time in marauding; and one day in 1708, being in male garb, she and her mule were taken prisoner. However, she persuaded the French officer to let her go. Shortly before this she hired herself as cook to the head sutler of the British army, Mr. Dupper, who afterwards kept a tavern on Fish Street Hill, London.
