Did Lee, Beauregard, and Davis Commit Treason?
No. Davis was hoping for a Trial that would allow him to prove the Constitution permitted Succession. Both Lee and Beauregard were employed by the U S Army at the time Virginia and Louisiana voted to secede.
Virginia originally voted to stay in the Union until Lincoln decided to send in troops through Virginia to put down the rebellion in South Carolina.
In Louisiana the popular vote was 53%-47% in favor of secession.

Is there a Federal Law protecting Monuments to Veterans?
There is, but only on Federal Land, we think New Orleans should put the same context into its City Charter.
