Lincoln cycles through Union generals (1862)
President Abraham Lincoln removed a string of commanders, including George McClellan, while searching for a general who would fight aggressively. He kept changing leadership until Ulysses S. Grant took overall command in 1864.
Each change brought turmoil and criticism, and some removed generals were popular with their troops.
The eventual choice of Grant produced the aggressive strategy that won the war for the Union.
It shows a wartime leader repeatedly changing commanders to find the right fit. Zelensky is running a similar search under battlefield pressure.
