Grant drastically changed the Union military strategy. Where his predecessors had focused on trying to capture Richmond, he would defeat the Confederate army.
Answer: Option A
<u>Explanation:</u>
Grant's union army pursued Lee's confederate army in the Overland Campaign, which resulted in an important victory for the Union army led by Grant. It was a battle fought in Virginia. Although, previously, the union army was keen to target Richmond, this time their goal was to destruct Lee's army.
After Grant was made the lieutenant general and got all command of the Union army, he sought to defeat Lee's army by inviting an open battle. The battle had many casualties from both sides.
Another battle was fought which is called the battle of North Anna, where Lee could have defeated Grant's army, but his illness prevented him from doing so. The final battle was fought at Cold Harbour, where Grant's army won the battle.
