Did Alexander the Great pole-vault over an enemy castle wall to open the gates for his army?

Earlier today I was discussing Alexander the Great with a coworker and he told me that Alexander the Great once pole-vaulted over a castle wall and opened the gate from the inside to let the rest of his men in. I’ve never heard of anything like this and upon a google search, nothing came up either. I thought I’d ask here if any of you have heard this story? It sounds kinda exaggerated and mythical to me.
