Could Britain Have Invaded Maine to Help the Confederacy in 1864?

It is unlikely that Britain would have sent 90,000 troops to invade Maine from Canada to help the Confederates in 1864. By that time, Britain had already recognized the Union and had abandoned its plans to support the Confederacy. Moreover, such an invasion would have been a direct act of war against the United States and would have provoked a strong response from the Union army. It is also unlikely that the Confederates would have been able to coordinate such an invasion with the British, as they were already struggling to defend their territory against the Union army. Ultimately, any attempt by Britain to invade Maine would have been met with resistance and likely would have resulted in a significant loss of life and resources for all involved.
