The troops procured a few boats around 2 a.m. for the crossing, but only 83 men made it to the other side of the lake before Allen and Arnold decided to attack, concerned that dawn was approaching. The small force marched on the fort in the early dawn, surprising the lone sentry, and Allen went directly to the fort commander's quarters, seeking to force his surrender. Lieutenant Jocelyn Feltham was awakened by the noise, and called to wake the fort's commander Captain William Delaplace. He demanded to know by what authority the fort was being entered, and Allen said, "In the name of the Great Jehovah and the Continental Congress!" Delaplace finally emerged from his chambers and surrendered his sword, and the rest of the fort's garrison surrendered without firing a shot. The only casualty had been a British soldier who became concussed when Allen hit him with a cutlass, hitting the man's hair comb and saving his life.
