Jean 19:32,33

Then came the soldiers and broke the legs--By no mode of judicial death has “man’s inhumanity to man” been more shown than by crucifixion.

It was a slow death by exhaustion and starvation. These processes were so slow, that when the crucified person was in ordinary health and vigour, invariably he survived the first twenty-four hours, lived generally over the second, occasionally even into the fifth or sixth day. “I was told,” says Captain Clapperton, speaking of the punishments in the Soudan, “that wretches on the cross generally linger three days before death puts an end to their sufferings.” In old times, at nightfall, when the crowd had gone home, and each head had found its soft pillow, the soldiers lighted their lanterns and waited. Through the frost of the night, through the fire of the day, then through another night and day, the man on the cross would be dying slowly, until the savage watchers, out of patience, would sometimes, not indeed for his sake, but for their own, by blow of mace or mallet, break his limbs; and the shock of this would shake out the last quivering spark of life. In this instance, besides the impatience of the soldiers, there was that of the people. Next day would be the Sabbath of the Passover, regarded as the great Sabbath of the year. According to their standard, it would have been desecration of this day if they had allowed a man to die on it by hanging on a tree. A deputation, therefore, waited on the governor, with an entreaty that the men who were on the crosses might be despatched at once, and their bodies taken away. He acceded to this; the order was forwarded to the soldiers; in carrying out this order they broke the legs, first of the malefactor on the one side, next of him on the other side of the central cross; but when they came to that they found that Jesus was dead already.
