The Cambridge Veterans’ Organization and the city’s Department of Veterans’ Services will hold their annual Patriots’ Day Observance at 10:45 a.m. Monday at the Washington Monument on the Cambridge Common.

The event will be highlighted by a reenactment of Patriot William Dawes Jr. historic horseback ride from Boston to Cambridge alerting the colonists of the British threat of 1775. Dawes, dressed in colonial garb, will deliver the alert to Mayor David Maher, who will speak at the event. A memorial wreath will be laid at Gen. George Washington’s monument, and the CVO Firing Team will give a rifle salute followed by the blowing of taps by bugler Greg Gettle.

Philip Anderson, the organization’s president, will serve as master of ceremonies, and city councilor Marc McGovern will deliver the keynote address.

A Cambridge Rindge & Latin School Drama student will read the Governor’s Patriots’ Day Proclamation. A CRLS music student will sing the National Anthem and “God Bless America.”
