In November and December of 1871, the Board of Police and Fire Commissioners conducted an investigation in an attempt to determine the cause of the Great Chicago Fire. Mrs. O'Leary testified before the Board on November 24, 1871. This is her testimony.

Q. What do you know about this fire?

A. I was in bed myself and my husband and five children when this fire commenced. I was the owner of them five cows that was burnt and the horse, wagon, and harness. I had two tons of coal and two tons of hay. I had everything that I wanted in for the winter. I could not save five cents worth of anything out of the barn, only that Mr. Sullivan got out a little calf. The calf was worth eleven dollars on Saturday morning. Saturday morning I refused eleven dollars for the calf, and it was sold afterwards for eight dollars. I didn't save one five cents out of the fire.

Q. Do you know how the fire caught?

A. I could not tell anything of the fire, only that two men came by the door. I guess it was my husband got outside the door and he ran back to the bedroom and said, "Kate the barn is afire!" I ran out and the whole barn was on fire. Well, I went out to the barn and upon my word I could not tell anymore about the fire. I got just the way I could not tell anything about the fire.

Q. You got frightened?

A. I got frightened. I got the way I did not know when I saw everything burn up in the barn. I got so excited that I could not tell anything about the fire from that time.

Q. Do you know the parties who first gave you the alarm? Who told your husband that your house was on fire?

A. It was Mr. Sullivan gave the first alarm to me. The party were there. They were up but none of them didn't come and call for me. I was left in bed.

Q. Who is Mr. Sullivan?

A. He lives over there in DeKoven Street.

Q. Opposite you on DeKoven?

A. Yes sir, right across the road.

Q. What does he do?

A. He is a drayman. There was a party in the front of our place that night. I could not tell whether it was them made the fire or not. I didn't see it. I was in bed.

Q. When you first saw the fire, was there anyplace on fire but your own barn?

A. There was, sir. It was catched along down before me. Mrs. Murray and Dalton have places was afire going together. The other side on Taylor Street and the rear of the alley. Both fires were going together.

Q. How many houses were on fire or sheds or barns at the time you first saw it?

A. At the time I first saw it, my barn was and Mrs. Murray's barn was afire and Mr. Dalton's little shed. That is all that was afire I think when I first saw it. I thought there was no more fire, only them places. Then I catched one of the children and put him out on the sidewalk. I thought there was no more places on fire, only our places down there, and I saw Turner's big block on fire, and I thought there wasn't a touch on Turner's block until then. I saw the fire from the inside break out from Turner's block.

Q. Inside?

A. It was breaking out through the inside of Turner's block.

Q. Where was Turner's block located?

A. It was on Jefferson, a little west from us.

Q. (By Mr. Williams) A long row?

A. Yes sir.

Q. On the corner?

A. Yes sir. I thought there was not a touch of fire at all, only where we were and Mrs. Murray's barn and Mr. Dalton's barn. I thought there wasn't any fire any other place until I saw the fire in Turner's block. Over at least two story houses next to Mrs. Murray there wasn't but one window burning at that time. That catched from Mrs. Murray's house one window. When I saw Turner's block going, I gave up all hope.

Q. By Mr. Chadwick. You thought your house was to burn then?

A. Yes sir. Then the men went and fixed two washtubs at both hydrants. There is a hydrant in front of our place and a hydrant in front of Mrs. Murray's. They set two washtubs and then began to put water on the little house. And everything was gone, only the little house and they made for that and kept it wet all through until the fire was gone.

Q. Is that your house?

A. Yes sir. They kept water on it until the fire went out. We had plenty of water until the fire was done.

Q. Did they state who the person was?

Q. Did you use them for bedding?

A. Yes sir. Not so much for bedding. I used to clean out the places and take a dish full and throw it in along with the cows.

Q. (By Mr. Brown) After you discovered the fire, can you state whether there was any engine on the ground or how soon after did you discover one?

A. The first engine I seen playing, it was on Turner's block.

Q. How long after you got outdoors was it before you saw the engine there?

A. I could not tell you exactly.

Q. Was it a very long time or very quick?

A. It was not very quick at all.

Q. Can you give some idea about how soon it got there?

A. Before I seen any engine there, our barn was pretty near burned down. The engine might be there unknown to me.

Q. Did you see the engine or did you first see it when they began to play water?

A. I did see the first playing of water on Turner's block.

Q. That is the first you saw of the engine?

A. Yes.

Q. (By Mr. Williams) Is there a fire hydrant for an engine to take water in the corner of Jefferson and DeKoven?

A. Yes sir.

Q. Did you see any engines standing there?

A. I did, sir.

Q. How soon was that engine at that hydrant?

A. I could not tell.

Q. About five minutes after you got out of bed?

A. I do not know. I wasn't five minutes after I got out of bed. I didn't get out in front. I went to the rear to see if I could save anything, because there was a new wagon standing in the rear of the alley between our place and Taylor. I went out to see if we could save the wagon. The other side was going just as well as our place, and we could not save the wagon.

Q. Both sides of the alley were on fire?

A. Both sides of the alley were on fire.

Q. Can you give us an idea about how great a length of time passed from your first hearing of the fire until you first saw the engine?

A. I could not, sir. The engine might be there unknown to me--I got so excited. All I had was there in that barn. I did not know the fire was down until the next day.

Q. Had you any insurance upon your barn and stock?

A. Never had five cents insurance--I had these cows, one of them was not in the barn that night. It was out in the alley. That one went away. I could not get that one. My husband spent two weeks looking for it and could not find it anywhere in the world. I could not get five cents. I had six cows there. A good horse there. I had a wagon and harness and everything I was worth, I couldn't save that much out of it (snapping her finger), and upon my word I worked hard for them.
