It always had more troops to replace its losses.
The South only had half the population - a third of them slaves.
After Grant ended the system of prisoner-exchange, the Confederates simply ran out of manpower, and had to surrender for that simple reason.
the jews secretly plotted against the muslims because they could not contain their anger after the battle of badr in which the muslims were victorious
I believe it was regarded as inconclusive, but it could be regarded as a win for the Germans because they inflicted many US casualties.
There were 3000 plus casualties of the Allied Force during the Seige of Bastogne in Belgium. I could not find a record for the Nazi deaths.
The North. A big reason for final Northern victory, as the Confederates could not replace their casualties.
There were over 3000 Allied Forces casualties (deaths) in the Battle of Bastogne. I could not find a number of the German deaths. It could be they don't even know how many Germans and Axis Forces troops died in that battle.
Their limited population - as wars continued and battle casualties added up, they simply could not field a decisive army, and ceded superiority to Thebes.
We have no specific evidence - just a comment from the main historian Herodotos: 'There were also Greek casualties, but not many; for most of the Greeks could swim'.
There was not a clear winner on Day One. One could argue a Confederate victory, but the Federal forces did seize the high ground and did not relinquish it. That proved to be the deciding factor in the battle.
The Battle of Gettysburg, fought July 1-3, 1863, was the bloodiest battle of the US Civil War. It produced over 50,000 casualties in dead, wounded, and missing combined between the two armies. The Confederacy lost 4,000 killed while the Union suffered 3,155 dead.
You do not specify what you are referring to. I will assume that you mean how many soldiers. A full strength legion had 5,120 infantrymen and 120 cavalry. However, the legion often were not at full strength. The legions were organised into cohorts (similar to battalions). it had 10 cohorts. Cohorts 2 to 10 had six centuries (the equivalent of a company) of 80 men each. The first cohort was larger and had 5 double size centuries (with 160 men each). This made a total of 59 centuries. It also gave a total of 4,230 men in the standard cohorts and 800 men in the 1st cohort. The entire legion had 5,120 infantrymen. T
After the Battle of Midway not really unless the Japanese could make the price of victory (in terms of casualties) too much for the U.S. to bear. They failed to do that despite desparate attempts.
The Battle of Flamborough Head, at which John Paul Jones, commanding the Bonhomme Richard successfully captured the British sloop-of-war Serapis, saw approximately 287 casualties, based on estimates and reports from the time. The Americans and French lost approximately 170 casualties; the British over 117. Remember that sailors could take days or weeks to slowly die from injuries/infections received from wounds in battle.
