How did Robert Newman and John Pulling Jr. escape the british after lighting two lanterns in the Old North Church

In the year 1775 during the great civil war, the British government and the American colonies could not come to an agreement on how to end the war. Both countries fought each other with their greatest weapons and best military officers. The British governor, General Thomas Gage was instructed by Great Britain to ensure that the American soldiers do not have access to any weapons so that they would be easily defeated.

On April 18, General Thomas ordered the British army to capture both Concord and Lexington. Paul Revere got the information from one of their spies about the British attack. William Dawes and Paul Revere were made to ride to both towns to warn them about the British invasion, both men were worried that they might not reach their destination in time to warn the malitia.

Paul decided to hatch out a new plan to get the message across at a faster rate, he met up with two men Robert Newman and John Pullings. They were both caretakers of the Old North Church, these men were directed to climb up to the church tower and light up lanterns at the window. One lit latern would mean that the British army would pass through a narrow land and two lit latern meant that they will pass through the river.

When the British Army ordered their navy officers to sail through the river, the colonists immediately knew how they planned to attack. The two men climbed up to the tower and lit the two lanterns for a period of sixty seconds to inform the troops who were awaiting their signal.

Robert Newman and John Pullings Jr. escaped by passing through the back window of the church and jumped down to the ground. Robert sneaked back to his house but was arrested the next day for questioning while John ran to Boston so that he would not get arrested.
