King's was defended by the college gun, re-equipped with a powerful hose pipe, whilst Phineas stood on the college's main steps with a personal bodyguard of engineering students armed with rotten fruit and vegetables from the nearby Covent Garden Market. Having taken the precaution to switch off the college's water supply at the mains, UCL students engaged their rivals resulting in several injuries and the collapse of part of a King's College stone balustrade. Police were called and a truce was enforced.
