Given the question: Found the following article online, use it to answer the question: What is the first name of the person whose surrender demand was made to Lieutenant Jocelyn Feltham?  In 1775, Fort Ticonderoga, in disrepair, was still manned by a token British force.  They found it extremely useful as a supply and communication link between Canada (which they had taken over after their victory in the Seven Years' War) and New York. On May 10, 1775, less than one month after the American Revolutionary War was ignited with the battles of Lexington and Concord, the British garrison of 48 soldiers was surprised by a small force of Green Mountain Boys, along with militia volunteers from Massachusetts and Connecticut, led by Ethan Allen and Benedict Arnold.  Allen claims to have said, "Come out you old Rat!" to the fort's commander, Captain William Delaplace.  He also later said that he demanded that the British commander surrender the fort "In the name of the Great Jehovah and the Continental Congress!"; however, his surrender demand was made to Lieutenant Jocelyn Feltham and not the fort's commander, who did later appear and surrender his sword.With the capture of the fort, the Patriot forces obtained a large supply of cannons and other armaments, much of which Henry Knox transported to Boston during the winter of 1775–1776.  Ticonderoga's cannons were instrumental in ending the Siege of Boston when they were used to fortify Dorchester Heights.  With Dorchester Heights secured by the Patriots, the British were forced to evacuate the city in March 1776. The capture of Fort Ticonderoga by the Patriots made communication between the British Canadian and American commands much more difficult. Benedict Arnold remained in control of the fort until 1,000 Connecticut troops under the command of Benjamin Hinman arrived in June 1775. Because of a series of political maneuvers and miscommunications, Arnold was never notified that Hinman was to take command.  After a delegation from Massachusetts (which had issued Arnold's commission) arrived to clarify the matter, Arnold resigned his commission and departed, leaving the fort in Hinman's hands.
The answer is:
Ethan
