No they didn’tUkraine adopted Siege tactics from day one
They adopted the tactic of holding and dropping back, destroying bridges etc, slowing the advance and giving others up the line a chance, and then would ultimately dissolve into an occupied resistance

What promises to the defenders of Mariupol?…...
The Ukrainian Government throughout the war has lied to its army and the west has played a dreadful part in that deceit, by supplying heavy weapons and cheering on the struggle and ask the blokes who defended Mariupol about promises..

This proved correct with the Russian advance ultimately having to retreat
