In 1894 the Lexington Historical Society petitioned the Massachusetts State Legislature to proclaim April 19 as “Lexington Day”. Concord countered with “Concord Day”. Governor Frederic T. Greenhalge opted for a compromise: Patriots’ Day. However the biggest battle fought on this day was in the town of Menotomy, now Arlington, Massachusetts. Menotomy was on the Concord Road between Lexington and Concord and Boston . While the fighting was going on in Lexington and Concord, 5,100 militia men arrived in Menotomy from Middlesex and Essex Counties . These men took up positions along the road the British troops would take on their retreat to Boston . They placed themselves in and around houses, stone walls, fields and barns. The bloodiest fighting of the first day of the American Revolution took place inside a single house, the Jason Russell House, in Menotomy . Eleven militia men died in this house fighting British troops trained in bayonet fighting .
