An example of George Washington's interest in intelligence analysis and estimates can be found in instructions he wrote to General Putnam in August 1777: "Deserters and people of that class always speak of number. ... Indeed, scarce any person can form a judgement unless he sees the troops paraded and can count the divisions. But, if you can by any means obtain a list of the regiments left upon the island, we can compute the number of men within a few hundreds, over or under." On another occasion, in thanking James Lovell for a piece of intelligence, Washington wrote: "It is by comparing a variety of information, we are frequently enabled to investigate facts, which were so intricate or hidden, that no single clue could have led to the knowledge of them. ... Intelligence becomes interesting which but from its connection and collateral circumstances, would not be important."
