As she was bending over a wounded rebel, he whispered to her: "Lady, you have been kind to me ... every street of the city is covered by our cannon. When your entire army has reached the other side of the Rappahannock, they will find Fredericksburg only a slaughter-pen. Not a regiment will escape. Do not go over, for you will go to certain death."
She thanked him for the kindly warning and later told of the call that came to her to go across the river, and what happened. She says:
"At ten o'clock of the battle day when the rebel fire was hottest, the shells rolling down every street, and the bridge under the heavy cannonade, a courier dashed over, and, rushing up the steps of the house where I was, placed in my hand a crumpled, bloody piece of paper, a request from the lion-hearted old surgeon on the opposite shore, establishing his hospitals in the very jaws of death:
"'Come to me,' he wrote. 'Your place is here.'
"The faces of the rough men working at my side, which eight weeks before had flushed with indignation at the thought of being controlled by a woman, grew ashy white as they guessed the nature of the summons, ... and they begged me to send them, but save myself. I could only allow them to go with me if they chose, and in twenty minutes we were rocking across the swaying bridge, the water hissing with shot on either side.
"Over into that city of death, its roofs riddled by shell, its every church a crowded hospital, every street a battle-line, every hill a rampart, every rock a fortress, and every stone wall a blazing line of forts.
"Oh, what a day's work was that! How those long lines of blue, rank on rank, charged over the open acres, up to the very mouths of those blazing guns, and how like grain before the sickle they fell and melted away.
"An officer stepped to my side to assist me over the débris at the end of the bridge. While our hands were raised in the act of stepping down, a piece of an exploding shell hissed through between us, just below our arms, carrying away a portion of both the skirts of his coat and my dress, rolling along the ground a few rods from us like a harmless pebble in the water. The next instant a solid shot thundered over our heads, a noble steed bounded in the air and with his gallant rider rolled in the dirt not thirty feet in the rear. Leaving the kind-hearted officer, I passed on alone to the hospital. In less than a half-hour he was brought to me—dead."
She was passing along a street in the heart of the city when she had to step aside to let a regiment of infantry march by. At that moment General Patrick saw her, and, thinking she was a frightened resident of the city who had been left behind in the general exodus, leaned from his saddle and said, reassuringly:
"You are alone and in great danger, madam. Do you want protection?"
