It is estimated that around 21 million people were wounded in World War 1.
The American and French forces lost 244 killed and another 584 wounded which was more then 10 percent of their combined forces. The defending British lost only 40 killed in action and 63 wounded. It was a major win for the outnumbered British.

ANSWER:After the Battle of Bunker Hill, which was on June 17, 1775, about 400 Americans and more than 1,000 British soldiers were killed or wounded.
In World War I, the Battle of Verdun claimed more than a million dead and wounded. It lasted more than nine months. The French claimed a strategic and tactical victory.
A little more than 21 million, and 8 million died
Gettysburg, but there were not 50,000 killed, there were 50,000 casualties. Casualties is killed AND wounded. Usually about four wounded for every one killed outright. Some of the wounded will die later, but most will recover, though perhaps not be able to fight any more. So probably somewhere around 10,000 were killed immediately, a few more thousand would die of wounds or infection later, the rest would suffer horribly but eventually live on.
