The 4th Infantry Division, in concert with the 9th and 79th Infantry Divisions, at13 tacked to seize Cherbourg.
The enemy was well fortified and put up fierce resistance.
At times maneuver units found themselves involved in 360-degree battles as Germans they had bypassed or overrun fired into their rear while they were continuing to attack to the front.
Supply trains and reinforcements required armored escorts until follow-on forces mopped up this residual resistance.
Artillery, air strikes, tanks, engineers and infantry were tightly integrated into attacks on one strong point after another.
By 25 June the division fought its way into Cherbourg itself, and cleared its sector in house-to-house fighting.
Here mines and booby traps proved as great a threat as enemy firepower.
When Cherbourg itself fell, the division turned its attention to reducing strong points around the perimeter bypassed during the advance.
The last of these surrendered on 29 June.
