David was so sure that his orders would be executed, that he did not think it necessary to specify any particular crime of which Uriah had been guilty.
Verse 16
The king's wishes were fully carried out by Joab. “When Joab watched (i.e., blockaded)the city, he stationed Uriah just where he knew that there were brave men” (in the city).
Verse 17
2Sa 11:17“And the men of the city came out (i.e., made a sally)and fought with Joab, and some of the people of the servants of David fell, and Uriah the Hethite died also.” The literal fulfilment of the king's command does not warrant us in assuming that Joab suspected how the matter stood, or had heard a rumour concerning it.

Joab immediately despatched a messenger to the king, to give him a report of the events of the war, and with these instructions: “When thou hast told all the things of the war to the king to the end, in case the anger of the king should be excited (תּעלה, ascend), and he should say to thee, Why did ye advance so near to the city to fight? knew ye not that they would shoot from the wall? Who smote Abimelech the son of Jerubbosheth (i.e., Gideon, see at Jdg 6:32)? did not a woman throw down a millstone from the wall, that he died in Thebez (Jdg 9:53)? why went ye so nigh to the wall? then only say, Thy servant Uriah the Hethite has perished.” Joab assumed that David might possibly be angry at what had occurred, or at any rate that he might express his displeasure at the fact that Joab had sacrificed a number of warriors by imprudently approaching close to the wall: he therefore instructed the messenger, if such should be the case, to announce Uriah's death to the king, for the purpose of mitigating his wrath. The messenger seems to have known that Uriah was in disgrace with the king. At the same time, the words “thy servant Uriah is dead also” might be understood or interpreted as meaning that it was without, or even in opposition to, Joab's command, that Uriah went so far with his men,
