Once the war between the states had begun, the college was active in support of the Union cause. Undergraduate classes, however, continued without diminution of numbers. Indeed, in the year of Gettysburg the largest classes up to that time entered Tufts. In all, sixty-three graduates of the college served in the blue of the Union armies, many with distinction. Winsor Brown French of the class of 1859 was made Brigadier General and was the first man to gain the heights of Fredericksburg. Tufts men also played an important role in the Spanish-American War and in the first and second world wars. The main entrance leading to the college and the beautiful new War Memorial Library are tributes to the men and women of Tufts who have served and died in our nation's wars. Tufts is proud of the fact that it has undergraduate Naval and Air Force Reserve Officers Training Corps Units and Army Reserve Officers Training Corps Units in its Schools of Medicine and Dentistry.
