Near Seneca in Montgomery County, Maryland — The American Northeast (Mid-Atlantic)
Rowser’s Ford
5,000 Confederate Cavalrymen Crossed
| — | Gettysburg Campaign | — |
That night, 5,000 Confederate cavalrymen crossed into Maryland at Rowser’s Ford, cutting between the Union army and Washington. The rain-swollen river made crossing difficult for artillery and ambulances. By 3 a.m. on Sunday, June 28, they had crossed without alerting residents.
Stuart seized the Chesapeake and Ohio Canal between Locks 23 and 24, hoping to disrupt commerce and an important Federal supply line. Cavalrymen turned a barge length-wise for an impromptu bridge. Capturing at least a dozen boats with Union soldiers and grain, they burned nine, damaged the wooden gates at Lock 23 and Guard Lock 2, and drained that section of the canal by breaching the towpath embankment. Not until June 30 was the canal again operational.
Stuart’s forces rested, then split into two columns to converge that afternoon at Rockville, the Montgomery County seat. Gen. Wade Hampton’s brigade turned up Seneca Road to Darnestown. Stuart, with the other two brigades under Gens. Fitzhugh Lee and W.H.F. Lee (led by Col. John R. Chambliss), rode south towards Offutts Crossroads (present-day Potomac) and onto Great Falls Road.
