They had to get there before the other side did, so that they could get an advance into making their trench, so before the other side come, they will be ready will their trenches!
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.
After the war the trenches went away as the land returned to its original uses, but I found a couple of them left that you can visit. One is Vieil Armand in Alsace, and the trenches were mostly carved in stone so they are well preserved. Also, World War 1 trenches in the Meuse have been restored to their original condition so that people can visit them. The German trenches there were built with concrete reinforcements, but the French trenches had filled in over the years and had to be dug out again.
Answer 1They were made of sandbags and dirt.Answer 2The trenches were dirty because they were dug out of the ground and were not properly irrigated or maintained. Trench building was a hasty production and most of the trenches in World War I were built in France where the soil is moist and gives way very easily, leading to small mudslides and the like.
Trench warfare dates back hundreds of years. It was an effective method of attacking a fortress. During the early age of artillery, the attacking forces tried to move their artillery close to a fort in order to breach the walls. The trenches were just a way to get closer without exposing the cannoneers to fire from the walls of the fort. The earliest trenches were built in the zig-zag pattern in order to make it harder to fire into the trenches from the side. This was seen in the World War I trenches. Trench warfare became a frequent military tactic for defending territory between the US Civil War (1861-1865) and the first World War (1914).
Because they were fighting a war!!!
Thessaloniki, or Salonika.
with trenching spades if they didn't dig quick enough they risked being shot

Many things made it possible to fire from the trenches. Mortars and field artillery were often fired from trenches. Trenches usually had berms (low dirt walls) built in front of them with firing positions along the top of the berm. Trenches sometimes had benches or ladders for gunners and snipers.
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.
To prtect the army from getting shot
Trench warfare was Intorduced in world war 1. By world war 2, really the end of ww1 on. they were outdated due to the use of tanks and their ability to roll over the barbed wire and trenches.
Tracks on tanks showed up in ww1 to allow them to cross trenches without getting stuck, America was the first to deploy them.

by digging trenches and connecting the rivers
they built trenches for procetion and they used it as a base.
The trenches were called saps and the people who dug them were called sappers.
