1. The plunging fire of a high position is not as effective as a sweeping fire of a low one.
2. It is not as easy to conceal our position.
The advantages of low ground, are:—
1. The low, sweeping fire that we get, especially when the ground in front is fairly flat and the view over the greater part of it is uninterrupted, is the most effective kind of fire.
2. As a rule it is easier to conceal trenches on low ground, especially from artillery fire.
3. If our trenches are on low ground, our artillery will be able to find good positions on the hill behind us without interfering with the infantry defense.
The disadvantages are:—
1. As a rule it will be more difficult to reënforce the firing line and to remove the dead and wounded from the trenches.
2. On a low position there will usually be an increase of dead space in our front.
