The Guys would mass on the edge of the town from daybreak on Guy Fawkes Night, wearing masks or bizarre disguises and armed with clubs and lighted torches. At nightfall they would enter the town and avenge themselves on those who had crossed them in the preceding year by committing assaults and damaging property, often looting the belongings of victims from their houses and burning them on bonfires in the middle of the street. In later years attempts to suppress the Guys led to the deaths of two police officers. In 1866 and 1868 the Guys were dispersed by cavalry and this seems to have brought an end to the riots. Similar disorder surrounding the St Catherine's Hill Fair, held just outside the town on the Pilgrims' Way, was suppressed around the same time. In 1906 the Guildford Union Workhouse Casuals Ward ("The Spike") was built on the grounds of the Workhouse near the castle; today The Spike is a tourist attraction. After the death of their father in 1882, brothers Charles Arthur and Leonard Gates took over the running of his shop, which held the local distribution franchise for Gilbey's wines and spirits, and also sold beer. However, in 1885, the brothers were persuaded to join the temperance movement, and they poured their entire stock into the gutters of the High Street. Left with no livelihood, they converted their now empty shop into a dairy. Using a milk separator, they bought milk from local farmers, and after extracting the cream and whey, sold the skim back to the farmers for pig feed. In 1888 three more of the Gates brothers and their sons joined the business, which led to the formal registration of the company under the name of the West Surrey Central Dairy Company, which after development of its dried milk baby formula in 1906 became Cow & Gate. In 1901, the Dennis brothers built the first purpose-built car factory in England. It was subsequently known as the Rodboro Buildings after being taken over by the eponymous shoe company in 1919. During World War II, the Borough Council built 18 communal air raid shelters. One of these shelters, known as the Foxenden Quarry deep shelter, was built into the side of a disused chalk quarry. Taking a year to build, it comprised two main tunnels with interconnecting tunnels for the sleeping bunks. It could accommodate 1000 people and provided sanitation and first aid facilities. Having been sealed since decommissioning in 1944, it has survived fairly intact. The quarry itself is now the site of the York Road car park, but the shelter is preserved and was occasionally open to the public though visits are now suspended.
