Yes. If it is not straight, then it is not a line.
it just a straight line
If it is not straight, then it is not a line.
The word straight does have an antonym, which is crooked. So perhaps a crooked line is the opposite of a straight line.
The length (distance) of a straight line always changes, the angle of a straight line is 180 degrees.
Front-line trenches were not dug in straight lines. Otherwise, if the enemy had a successive offensive, and got into your trenches, they could shoot straight along the line. The French tended to build zig-zag trenches. However, the British Army preferred a system where each trench was dug with alternate fire-bays and traverses. Whereas fire-bays were straight sections of trenches, traverses were built at angles. This limited the effect of enfilade fire or shell-burst
zigzag to have better move avoiding direct contact fire and maintaining distance between units. Straight line less mobility of movement
Because the way that the succors are built
Frontline trenches were usually about seven feet deep and six feet wide. The front of the trench was known as the parapet. The top two or three feet of the parapet and the parados (the rear side of the trench) would consist of a thick line of sandbags to absorb any bullets or shell fragments. In a trench of this depth it was impossible to see over the top, so a two or three-foot ledge known as a fire-step, was added. Trenches were not dug in straight lines. Otherwise, if the enemy had a successive offensive, and got into your trenches, they could shoot straight along the line. Each trench was dug with alternate fire-bays and traverses. Duck-boards were also placed at the bottom of the trenches to protect soldiers from problems such as trench foot. Soldiers also made dugouts and funk holes in the side of the trenches to give them some protection from the weather and enemy fire. The front-line trenches were also protected by barbed-wire entanglements and machine-gun posts. Short trenches called saps were dug from the front-trench into No-Man's Land. The sap-head, usually about 30 yards forward of the front-line, were then used as listening posts. Behind the front-line trenches were support and reserve trenches. The three rows of trenches covered between 200 and 500 yards of ground. Communication trenches, were dug at an angle to the frontline trench and was used to transport men, equipment and food supplies.
Trench warfare used several different types of trenches. Firing trenches were used by soldiers to protect themselves while firing their weapons at their enemy. Cover trenches were often built next to the firing trenches as a second line of defense in case the enemy captured the firing trench. Support trenches were used as rest areas for off-duty troops, who sometimes lived in dugouts excavated in the sides of the trench. A network of reserve and communications trenches was used to bring supplies and fresh troops to the front.
most combatants at that time NEVER built straight trench's. 1. If a shell struck in to the trench, the shrapnel would go flying everywhere in the trench if it was in a straight line, the "curve" in the trench would deflect the shrapnel. 2. if part of the trench was overrun, resistance could still continue with a zigzag trench. If it was in a straight line, enemy soldiers could just fire there guns in a straight line and kill everyone easily.
the allies soon realized that they could not not break through this line, they also began to dig trenches.
The Maginot Line was a series of bunkers, gun emplacements, trenches, barbed wire, etc built by the French in an effort to keep the German military from invading France. It failed.
communication trench links the front line and first support line trench supports trench.
They were the western front. But the different trenches were front line trenches, communication trenches.
They were not dug in straight lines, because both sides used artillery to bombard one another. If an artillery shell hit a trench in a straight line it could wipe out a lot of soldiers, as the its blast could not be contained. A trench is made in that jaggerd format because if an artillery shell hits the trench it can be stopped by the structure and walls of the trench. The explosion in a straight line can get a lot futher than if a wall is in the way. Also the structure can be complicated to confuse the enemy if they ever manage to get into the trench.
The trenches on the western front were built in a more or less continuous line from the North Sea all the way to the border of Switzerland. A distance of about 750 km; considering that both sides used multiple trench lines, plush support trenches, and zigzags across the landscape there would have been several thousand kilometres of trenches being used by either side at any given time.
