Hi- great question. In short, yes. This a period of tactical organization that we broadly call, "linear warfare" as infantry and cavalry soldiers were often deployed in long and shallow formations of ranks and files on the battlefield. Despite this, whenever troops fought over urban environments, siege warfare employed a geometric system of trenches. This was complete with occasional attacks on the trenches by the opposing side, and artillery fire to silence enemy battery positions.

Beyond siege warfare, when an army felt threatened in the open field, they would often entrench in order to protect their position. (Bunzelwitz 1761, Valley Forge 1777-1778, Yorktown 1781) This could occasionally lead to field armies becoming besieged in trench warfare, as happened at Yorktown during the American War of Independence.

Building entrenched camps was a skill that most major armies cultivated during this period across the Atlantic World. One of the best examples of this is Frederick II of Prussia's camp at Bunzelwitz in 1761, where the entire Prussian army was ringed by entrenchments, complete with a primitive type of anti-personnel mines.
