Which outcome occurred when Roman siege towers approached fortified walls composed of mortared stone during medieval era conflicts?

💡 Explanation

When approaching walls, siege towers faced flaming projectiles because the close proximity made towers highly susceptible to fire damage during medieval warfare with stone walls. Therefore tower vulnerability increased rather than toppling reduction, enhanced mobility, or decreased structure, requiring fundamentally different constructive countermeasures regarding combustion and projectiles.
