The battle of Saratoga was a turning point in the American Revolution simply because, with their defeat of the British, the colonists showed that they were willing to fight for their freedom, and because of this, they won the support of European allies, like France and Spain. France later proved to be essential at the Battle of Yorktown because it was the French fleet that blocked in Cornwallis' troops, preventing him from escape, which of course caused him to surrender, ending the Revolution.
Answer:
A trench war or position war is a war in which both parties have buried themselves opposite each other in trenches and other fortified positions, with the aim of stopping the advance of the enemy, which has resulted in a stalemate in which neither party succeeds through the enemy lines to break. In fact, a trench war is a situation where both sides besiege each other. Normally in the case of a siege there is an attacking party besieging the defending party, but in a trench war both parties are besiegers and besieged at the same time.
The best known trench war is the First World War (1914-1918), but wars such as the Civil War (1861-1865) and the Russian-Japanese War (1904-05) also exhibited characteristics of trench wars.
Nowadays trench wars only occur in the Third World, where the warring parties have modern firearms but hardly any vehicles such as tanks and planes. In the conflicts between Ethiopia and Eritrea at the end of the 20th century, trench wars were also waged.
