entrance and capturing a number of prisoners, but the fire from the enemy's rifle pits in rear of the fort, and the lack of reinforcements coming to their aid, rendered the place untenable. Sergeant Griffith and David Trine, of Company I, were the only survivors of this daring exploit. Only two men of the 22nd Iowa who entered the fort survived. This was the last frontal assault of Fort Beauregard ever attempted. Afterwards Vicksburg was defeated using long term siege tactics. The 22nd Iowa's losses at Railroad Redoubt were heavy. Of the 200 engaged in the assault, 42 were killed or died of their wounds, 128 wounded and 19 captured. Theirs was the highest toll suffered in any regiment of Grant's army in the siege of Vicksburg. Sergeant Leonidas M. Godley of Company E, although gravely wounded, survived the assault and was awarded the Medal of Honor in 1894 for his actions during the assault. In the end, the Confederate position held, bringing on the Siege of Vicksburg. References Redoubts Mississippi in the American Civil War
