But a curious thing took place. The Confederates got the Queen of the West off the mud, and tried to raise the Indianola and stop its leaks.

While they were hard at work at this they heard a frightful roar from the Vicksburg batteries. Looking up stream they saw a big boat coming down upon them at full speed. When they saw this they put the two big guns of the Indianola mouth to mouth, fired them into each other to ruin them, and then ran away. But weren't they vexed afterward when they learned that the boat that scared them was only a dummy which Porter's men had sent down the river in a frolic.

After that, the river batteries did not give the ships much trouble. When the right time came Porter's fleet ran down the river through the fire of all the forts. One boat caught fire and sank, but all the rest passed safely through. This was done to help General Grant, who was marching his army down, to get below Vicksburg.

I suppose all readers of American history know about the great event of the 4th of July, 1863. On that day Vicksburg was given up to the Union forces, with all its forts and all its men. Five days afterward Port Hudson surrendered. Porter and his boats now held the great river through all its length.

But there is something more to tell about Admiral Porter, who was a rear-admiral now.

In the spring of 1864 General Banks was sent with an army up the Red River. He was going to Shreveport, which is about four hundred miles above where the Red River runs into the Mississippi. Porter went along with his river fleet to help.

Now, no more need be said about Banks and his army, except that the whole expedition was only a waste of time, for it did no good; and there would be nothing to say about Porter and his fleet, if they had not gotten into a bad scrape which gave them hard work to get out.

The boats went up the river easily enough, but when they tried to come down they found themselves in a trap. For after they had gone up, the river began to fall and the water came to be very low.

There are two rapids, or small falls, on this part of the Red River, which show only at low water. They showed plainly enough now; and there were twelve of the boats above them, caught fast.

What was to be done? If they tried to run down the falls they would be smashed into kindling wood. It looked very much as if they would have to be left for the Confederates, or set on fire and burned.
