German artillery during the Battle of the Marne.

The following tables provide highly aggregated approximate figures for 15 battles of World War One with German participation; ten on the Western Front, and five on the Eastern Front against Russia. Of the ten battles in the West were mainly four against Frenchmen, five mainly against British and one battle fought against the Americans.
For all these battles, the date, its well-known names, the duration, the main units involved and the operational objective – ie attack or the three variants of the defense (rapid, preparing and defense of field fortifications) – are indicated.

The next series of numbers indicates the approximate strength of the opposing forces. The fourth row shows rounded the generally accepted losses of the opponents. The four battles on the Eastern Front brought the Germans an unusually high number of POWs. Therefore, in square brackets, the values without POWs are given.
The fifth row shows the casualty figures per day.
The sixth row shows the losses per day in per cent, based on the already specified strength at the beginning of the battle.

The next row is called scor, which is a score or grade based on the evaluation of the previous figures. This value indicates the losses per day as a percentage of the forces that caused these losses; it is determined by setting the losses of one side to the total personnel strength of the other side. Thus, the value shows losses per day per 100 men.
In brackets the score effectiveness modifies the score value to the adjusted approximately determined defenders advantage. Here, a factor is applied, which resulted from extensive research of WW2 , which have not yet been thoroughly examined with regard to World War One.
The defender advantage is in rapidly equipped defense adopted by 1.3, 1.5 for prepared defense and 1.6 for defense with field fortifications.

In some early battles of the war, as both sides attacked and therefore also partly defended rapidly, this factor is estimated at 1.2. The so devoted score effectiveness therefore reflects the normalized ability of both sides to inflict losses in the battles concerned.
The low value for long battles clearly shows what reflects all detailed examine about WW2: The Battle value index of all troops decreases constantly in long battles.
